One small tip: if you're not sure whether a hotel belongs to one of these collections, scroll to the bottom of its website. You'll often find the collection's logo in the footer, even when it's barely mentioned anywhere else on the site.

Small Luxury Hotels of the World was founded in 1990, just as the idea of the "boutique hotel" was beginning to reshape the industry. Instead of large, standardized properties, SLH focused on smaller, independently owned hotels where the personality of the owner, the building, and the destination could remain part of the experience.

Today, SLH includes more than 700 independently owned boutique hotels across 100+ countries. The average property has just 50 rooms, making this a noticeably more intimate collection than LHW or Preferred Hotels & Resorts.

The large portfolio is surprisingly easy to navigate. Hotels can be searched by the type of trip you're looking for, with categories such as Adults Only, Beach Resorts, Family Friendly, Honeymoon, All-inclusive, Private islands, Wine experience, etc. It's a useful way to discover smaller hotels you might never find when searching for a destination on your own.

Some recognizable members include Reschio Hotel in Umbria, Nimb Hotel Copenhagen, Canaves Oia Suites in Santorini, Cap Rocat in Mallorca, Dar Ahlam in Morocco, and Kenoa Resort in Brazil.

Small size doesn't mean lower standards. Every SLH property is inspected annually against more than 750 criteria, but there is no standard design or hotel formula to follow. The collection ranges from historic mansions and small city hotels to private islands, safari lodges and remote mountain retreats.

One of the biggest changes for SLH came through its exclusive partnership with Hilton. Participating SLH hotels can now be booked through Hilton, allowing Hilton Honors members to earn and redeem points and receive their usual status benefits. This gives independent boutique hotels something they traditionally couldn't easily offer: access to one of the world's largest hotel loyalty programs without becoming Hilton hotels themselves.

SLH also has its own complimentary loyalty program, The Club by SLH, with member rates and benefits when booking directly through the collection.

🛎️ Who it's for: Travelers who prefer smaller boutique hotels and unusual stays, especially if they already use Hilton Honors

The oldest collection in this guide, The Leading Hotels of the World (LHW) was founded in 1928 by 38 independent European hoteliers as The Leading Hotels of Europe. Their goal was to introduce Europe's leading hotels to the growing number of affluent American travelers crossing the Atlantic.

More than 60 member hotels are shareholders in the company, and nearly 90% of Leading Hotels are family-led, many of them for generations. This helps explain why the collection includes so many historic hotels with very distinct identities rather than properties designed around a single brand formula.

Several founding members are still part of LHW today, including Le Negresco in Nice, Hotel de Paris Monte-Carlo, Hotel Hermitage Monte-Carlo and Hotel Royal - Evian Resort.

Today, LHW includes more than 450 luxury hotels across 80+ countries. Recognizable members include The Ritz London, La Mamounia in Marrakech, The Lanesborough in London, Le Sirenuse in Positano, Beau-Rivage Palace in Lausanne, and Hotel Fasano Rio de Janeiro.

Membership is highly selective. A hotel needs a referral from an existing LHW member before it can apply, and only about 5% of hotels that inquire about membership are accepted. All members are five-star properties, but there is no shared design or hotel concept they have to follow.

LHW also has its own free loyalty program, Leaders Club. Members earn points toward future stays and receive benefits such as breakfast, possible room upgrades and flexible check-in and check-out. In 2026, American Express added Leaders Club as a Membership Rewards transfer partner in the U.S.

🛎️ Who it's for: Travelers who want a five-star hôtel with history and individual character, but still value the benefits and points system of a global hotel program

Relais & Châteaux started in France in 1954 with just eight independent hotels and restaurants along Route Nationale 7 between Paris and the French Riviera. Marcel and Nelly Tilloy, owners of La Cardinale, brought the properties together under the name Les Relais de Campagne and promoted the journey between them as "La Route du Bonheur," or The Road of Happiness. One of those original eight, Auberge des Templiers, is still a member today.

The group merged with Châteaux Hôtels et Vieilles Demeures in 1974 to form what became Relais & Châteaux. Today, it includes around 580 independently operated hotels and restaurants around the world.

Notable hotels include Saint James Paris, Château de la Chèvre d'Or on the French Riviera, Il San Pietro di Positano in Italy, Auberge du Soleil in Napa Valley, and the Ellerman House in South Africa.

Its identity has traditionally been summed up by the "5 C": Character, Courtesy, Calm, Charm and Cuisine. The last one is especially important. Food isn't simply an amenity at Relais & Châteaux; it has been part of the association's identity from the beginning. Today, its members collectively hold 347 Michelin stars, including 42 Green Stars.

That makes Relais & Châteaux noticeably different from other collections. A beautiful hotel alone isn't really the whole idea here. The restaurant, local ingredients, regional culinary traditions, and the connection between food and place are a major part of what the collection represents.

Relais & Châteaux still creates "Routes du Bonheur," itineraries connecting member properties and destinations, continuing the same idea that started with the road from Paris to the Riviera more than 70 years ago.

🛎️ Who it's for: Food-focused travelers who often choose a hotel partly for its restaurant, and love smaller properties with a strong connection to their region.

P. S. I've also written about my own experience staying at Relais & Châteaux properties and what I think makes them special. You can read it here.

Preferred Hotels & Resorts started in 1968, when 12 North American hoteliers created the Preferred Hotels Association as a referral network for independent properties. The company grew considerably over the following decades and has been owned by the Ueberroth family since 2004.

Today, Preferred Hotels & Resorts is representing more than 650 independent hotels, resorts and residences across more than 80 countries.

Notable members include Passalacqua and Grand Hotel Tremezzo on Lake Como, Finca Cortesin in Spain, Ojai Valley Inn in California, Baccarat Hotel New York, Pulitzer Amsterdam, Das Edelweiss Salzburg Mountain Resort in Austria, and Dromoland Castle Hotel in Ireland.

One thing that makes Preferred different from other collections is its range. The portfolio is divided into four collections:
1. Legend - highest luxury level
2. L.V.X. - focused on upscale luxury
3. Lifestyle - more approachable luxury with a strong sense of local style
4. Preferred Residences - includes villas, apartments and other residential-style stays

So seeing the Preferred Hotels & Resorts name doesn't necessarily tell you exactly what level of hotel to expect. It's worth checking which collection the property belongs to.

Hotels are required to meet the Preferred Standards of Excellence and undergo anonymous annual on-site inspections by independent third-party experts. This allows properties to keep their own identity while giving guests some assurance that they meet the collection's quality standards.

Preferred also has a traditional loyalty program - I Prefer Hotel Rewards. Members earn points, access member rates, and receive additional benefits when staying at participating properties across the collection.

🛎️ Who it's for: Travelers who want the widest choice of independent hotels, from approachable luxury to landmark properties, with a loyalty program that works across them

Founded in the UK in 2016 as Iconic Luxury Hotels, the group was originally built around a small collection of distinctive British properties. Over time, it expanded beyond the UK, starting with Hotel Excelsior Venice Lido as its first international addition.

In 2026, Iconic Luxury Hotels evolved into Iconic Hotels & Resorts, bringing together properties from the former Iconic portfolio and L+R Hotels under one platform. Today, the portfolio includes 11 hotels within the collection, along with four additional properties operated by it.

Among its best-known properties are Chewton Glen in Hampshire, Cliveden House in Berkshire, The Lygon Arms in the Cotswolds, 11 Cadogan Gardens in Chelsea, The Mayfair Townhouse in London, Palm House in Palm Beach and Gran Marbella Resort & Beach Club in Spain.

Each has its own history and identity, and unless you look closely, you may not immediately realize they belong to the same hotel group.

Unlike membership collections such as Relais & Châteaux or LHW, hotels don't apply to join Iconic Hotels & Resorts. It's an owner-operator rather than an association of independent hotels, so properties become part of the portfolio through ownership, investment or management agreements.

Iconic Hotels & Resorts is selective about what it adds, focusing on hotels with a strong individual identity and a sense of place rather than turning them into one standardized brand. That's why a hotel such as Chewton Glen can be part of Iconic Hotels & Resorts while also independently qualifying for membership in Relais & Châteaux.

🛎️ Who it's for: Travelers looking for distinctive luxury stays within a much smaller collection, particularly in the UK and Europe

Swiss Deluxe Hotels is a little different from the other collections in this guide. Rather than operating internationally, it brings together some of the leading five-star hotels within one country: Switzerland.

Founded in 1934, the association today includes 42 hotels and represents more than 40% of Switzerland's five-star hotel capacity.

Recognizable members include Badrutt's Palace and Kulm Hotel in St. Moritz, The Dolder Grand in Zurich, The Alpina Gstaad, Hotel Splendide Royal Lugano, and The Chedi Andermatt.

What makes the collection particularly interesting is the mix of independent hotels and properties that are already part of major luxury hotel groups. Alongside independent names, you'll find Four Seasons Hotel des Bergues, several Mandarin Oriental properties, Fairmont Le Montreux Palace, and The Park Gstaad, a Four Seasons Hotel.

So Swiss Deluxe Hotels is another good example of how hotel affiliations can overlap. Membership doesn't replace an existing hotel brand or group. Instead, it serves as an additional mark that connects some of Switzerland's leading luxury hotels, regardless of who operates them.

The collection is also useful when planning a trip around Switzerland. Its hotels span 24 destinations, and the website lets you browse them by interests such as Family, Gourmet, Wellness, Summer & Winter Sports, Golf, and Romance.

🛎️ Who it's for: Travelers planning a luxury trip through Switzerland who want an easy way to find established five-star hotels without limiting themselves to one hotel brand or international collection

Since 2024, there's another hotel distinction worth knowing about: Michelin Keys. Unlike Relais & Châteaux, LHW, or SLH, this isn't a collection you join. The Michelin Guide independently evaluates hotels and awards One, Two, or Three Keys to those it considers exceptional.

Hotels are judged on five criteria: architecture and design, quality and consistency of service, personality and character, value, and the hotel's contribution to the destination's experience. The system works much like Michelin Stars in one important way: One Key marks a very special stay, Two Keys an exceptional one, and Three Keys the most extraordinary hotels in the Guide.

What makes Michelin Keys relevant here is that they sit atop all the affiliations we've just discussed. A hotel can belong to Relais & Châteaux, LHW, or SLH and still earn a Michelin Key independently. Others have no collection affiliation at all.

So when you see both a collection logo and Michelin Keys attached to the same hotel, they tell you two different things. The collection indicates which broader hotel community the property belongs to; the Keys are Michelin's independent assessment of the hotel itself.
