WHERE TO STAY Idle away at the Little Palm Island Resort & Spa (from $1,190 per night; littlepalmisland.com) — it's on its own tiny islet 120 miles from Miami. On a budget? Try the Coconut Palm Inn (from $209 per night; coconutpalminn.com) on laid-back Key Largo.
WHAT TO DO Home to the continental United States' only living coral reef, the area has killer scuba diving.

Traveling on the Golden Eagle Trans-Siberian Express luxury train (gwtravel.co.uk) on its 15-day route across Russia.
Weekend substitution: We've got two options for this one.
WHERE TO STAY If you're mostly into the winter wonderland train idea, then take a scenic rail ride from New York City to a luxe B&B in Vermont, such as Twin Farms (from $1,300 per night, all-inclusive; twinfarms.com). On Amtrak's Ethan Allen Express (amtrak.com), it takes five-and-a-half hours to travel from Manhattan's Penn Station through the pretty Hudson River Valley to Rutland, Vermont. In nearby Barnard, the snow-globe-like Twin Farms awaits with a gourmet chef, a 20,000 bottle wine cellar, and museum-quality art.
WHAT DO TO If it's really Russia and vodka that you're after, skip the train and get your falsetto on at Jelsomino (jelsomino.us), New York City's franchise of the famed Moscow karaoke den, where Russian Standard and caviar reign supreme.
Weekend substitution: Puerto Rico, a two-and-a-half hour flight from Miami.

Weekend substitution: Yellowstone National Park, with its 2.2 million acres, is an hour drive from the airport in Jackson, Wyoming.
WHERE TO STAY The park is secluded in the winter: Only one lodge, the Xanterra-managed Mammoth Hot Springs (from $125 per night; yellowstonenationalparklodges.com), is open from January to March and reachable by car.
WHAT TO DO Have Xanterra arrange a cross-country skiing, snowshoeing, or snowmobiling excursion where you can look for elk, red foxes, gray wolves, and bison. Unfortunately, you're probably not going to see a grizzly bear — they hibernate in the winter.
