If you're carrying a laptop into the Bahamas, you must fill out a Declaration of Value form upon arrival, noting make, model, and serial number. Bring an extra battery. They're not always readily available in out-of-the-city locations. Bahamian electrical current is compatible with U.S. computers. If you're traveling from abroad, pack a standard adaptor.

If Internet service is an important consideration to you, ask your hotel representative about service before traveling.
