20 to Watch: 2010's Best Up-and-Coming Hotels

Ritz-Carlton Reserve Phulay Bay
Krabi, Thailand

Set in Krabi, the much quieter neighbor of tourist-heavy Phuket, the Ritz-Carlton’s 54 one-bedroom pavilions and villas have outdoor baths and private plunge pools; guests can take in the tropical garden or ocean views from a lounge bed on their veranda. For those feeling more adventurous, personal butlers are on hand to arrange evening boating excursions or Thai cooking classes. Doubles from $600.
