Side-by-side
Aman
Founded: 1988 (Amanpuri, Phuket). Portfolio: around 35 hotels and resorts across some 20 countries as of mid-2026 (Aman Summer Palace, Beijing left the brand in late 2025; Amanvari in Baja, Mexico opens August 2026). Owner: Aman Group (privately held).
Operating philosophy: refined privacy. Aman properties emphasise restraint, natural materials, restrained palettes, low-profile architecture. The defining ultra-luxury brand for "quiet luxury."
Six Senses
Founded: 1995. Headquartered: Bangkok. Portfolio: 27 hotels in 20 countries, with one of the largest pipelines in luxury hospitality. Owner: IHG (acquired 2019).
Operating philosophy: wellness-luxury. Every property has serious spa, structured wellness programmes, and an environmental ethos. The defining brand for "wellness luxury."
One&Only
Founded: 2002. Headquartered: Dubai. Portfolio: 14 resorts. Owner: Kerzner International.
Operating philosophy: scale luxury. One&Only properties emphasise high-amenity, high-energy resort experiences, from the 40-villa Emirates One&Only Wolgan Valley to sprawling beach estates with multiple restaurants and kids' clubs. The defining brand for "scaled ultra-luxury."

Where each brand fails

- Group celebration trips (the energy is wrong)
- Business travel (urban properties limited)
Six Senses
Weak for:
- Travellers who do not want wellness focus
- Traditional luxury without environmental orientation
- Urban hospitality, a young muscle: Six Senses Rome came in 2023 and Six Senses London opened only on 1 March 2026, at The Whiteley in Bayswater
One&Only
Weak for:
- Privacy-focused trips (the larger scale produces less seclusion)
- Wellness-led trips
- Quieter couples' celebrations

What about other ultra-luxury alternatives
Three brands also operate in the ultra-luxury tier:
- Bvlgari Hotels: smaller portfolio, contemporary Italian luxury
- Cheval Blanc: LVMH-owned, French refinement
- Soneva: barefoot-luxury Maldivian / Thai
Each is a credible alternative depending on the specific destination and trip type.
Five rules for ultra-luxury brand selection
- Match brand philosophy to occasion type
- Verify the specific property within the brand (Amangiri in the Utah desert differs sharply from Aman Tokyo)
- Use luxury travel agents (Virtuoso, FHR) for amenity stacking
- Only Six Senses earns points, via IHG One Rewards; Aman runs no loyalty program, and One&Only perks come through travel-advisor channels
- The booking lead time at top properties is 12-18 months for peak season

Frequently asked questions
Which is the most exclusive: Aman, Six Senses or One&Only?
Aman. Its roughly 35 resorts mostly run under 50 keys, rates sit at the top of the category, and the brand cultivates near-total privacy. Six Senses and One&Only are still ultra-luxury but larger and more sociable by design.
Do any of these brands earn hotel points?
Only Six Senses. As an IHG brand since 2019, its stays earn and redeem IHG One Rewards points. Aman runs no loyalty program at all, and One&Only's best extras come through luxury travel-advisor channels rather than a points scheme.
Which brand is best for families?
One&Only. Its resorts are built around variety: multiple restaurants, water sports, kids' clubs and space for groups. Six Senses is the warmer of the other two for children; many Amans cultivate an adult, hushed atmosphere better suited to couples.
Which brand is best for a wellness trip?
Six Senses, for structured programs: arrival screenings, sleep and nutrition plans, large spas and built-in sustainability. Aman's spas are superb but treatment-led rather than program-led; One&Only treats wellness as one amenity among many.
How many resorts does each brand have?
As of mid-2026: Aman has around 35 hotels and resorts across some 20 countries; Six Senses has 27 open in 20 countries with a large signed pipeline; One&Only runs a collection of 14 resorts under Kerzner International.
Which is the most expensive?
Aman, generally. Entry rates commonly start around $1,400-$2,500 per night and run far higher in peak season. Six Senses and One&Only sit in the same ultra-luxury tier but usually open lower, and the Six Senses points angle can cut the effective cost.
