Islamorada, Florida
You get the feel of the Caribbean without leaving the States -- including pale blue water that teeters at 70 degrees in cooler months and around 80 degrees in summer.
What to do: Exchange flirty glances while getting a couple’s massage in an oceanfront tiki hut at Cheeca’s spa. Then put those muscles to work on the resort’s nine-hole golf course designed by golf pro Jack Nicklaus (or get competitive at night on one of the six lighted tennis courts). End the evening with a romantic dinner at one of Morada Bay Beach Café’s oceanside tables -- and be sure to try the locally caught Wahoo with Cous Cous, MoradaBay-Restaurant.com
Good to know: Crowds are at their peak from mid-December to early April, so make hotel and restaurant reservations at least a month beforehand if you’re traveling then.
