One&Only Palmilla, Los Cabos

Set on the tip of Mexico's Baja peninsula, One&Only Palmilla is luxury at its finest. First, there's the emphasis on individual service that makes this big resort feel like a boutique hotel (guests are called by name, for example). Then, there's dining—celeb chef Jean Georges Vongerichten heads up its Market restaurant, which turns out tuna "ribbons" in a chipotle glaze. Finally, there's romance—concierges have been known to arrange moonlit guitar serenades on private sandy coves. The 172 airy rooms (and one villa) have red-tile roofs and floor-to-ceiling windows facing the Sea of Cortes; other sleeping options include the shaded daybeds on private balconies (those are good for a midday siesta). For families, a meandering river connects the kids' pool to an infinity pool where Mom and Dad can gaze at the turquoise sea and golden sands.
