In a way, a Caribbean vacation is one big spa trip. Lounging on a cushy daybed or a palapa-roofed terrace on a spectacular beach does instant wonders for melting stress far, far away.

(You might be surprised at how much more effective a massage can be when it's given in an open-air hut at the top of a cliff overlooking the sea…)
