-Do negotiate your taxi fare (or ask the driver to turn on the meter) before climbing in.
-Don't be surprised if you're called "Darling" or "Honey" in the Bahamas. It's as common a greeting in the Bahamas as "Mon" is in the Caribbean.
-Don't plan to sunbathe nude or camp on beaches: These are illegal activities in the Bahamas (though topless bathing is tolerated in some areas).
-Don't worry about changing money if you're a U.S. citizen. The U.S. dollar is on par and accepted along with the Bahamian dollar.
-Do experience the less touristy side of the Bahamas: Travel between islands on a mail boat. Your companions will be Bahamians (and sometimes their goats and chickens).
-Don't expect to find full banking services on all islands. Make sure you have enough cash or traveler's checks if you go beyond Nassau or Freeport/Lucaya.
-Do get a Bahama cell phone rental so you can stay in touch and coveniently get important information during your stay.
