The Bahamian dollar is based on the U.S. dollar and is interchangeable. Just try to use small U.S. bills so you don't end up with too much Bahamian currency before you leave the island -- elsewhere it's worth little. From all-inclusive resorts and posh condos to rental cottages and cheap hotels, there are bargains to be had, just not during the holidays or spring break. Try the conch for cheap eats and ask around for who's baking Bimini bread -- you can buy it hot, right from their kitchen table if you're an early riser.
The Bahamas often find themselves in the path of hurricanes from June through November, but many hotels offer a refund if you have to cancel for a hurricane, and if you're caught there in one, you'll get the lowest possible rate. Although rare, it can get chilly during January and February, and many restaurants and entertainment venues are shuttered in these off-season months on the more remote islands. May and June are the rainy months, especially in the northern islands. Junkanoo, held on December 26 and January 1, is free, fun and noisy, with the biggest parade taking place on Bay Street in Nassau.
