Good to Know
Aman Tokyo
- Musashi by Aman is the hardest reservation in the hotel by far — request it when you book your room, not after arrival, given how few counter seats it holds each night.
- Aman Tokyo shares its Kerry Hill design lineage with Aman Kyoto and Amanpuri; guests who know either property will recognise the material language immediately.
- Otemachi is a business district that empties out on weekends and after dark — quiet in a way that suits the hotel's register, but plan an evening in Ginza (a five-minute taxi) if you want street-level energy.
- The onsen-style spa pool is naturally lit and genuinely rare for central Tokyo — worth booking a treatment around daylight hours rather than in the evening.
One&Only Kéa Island
- Transfers, children’s programming, and villa-host service differ meaningfully by property.
- Resort credits and breakfast can be valuable on advisor rates, but compare package inclusions first.
- Reserve signature restaurants and high-demand excursions before travel.
