To enter the Bahamas you'll need two things: proof of citizenship and a return or onward-bound ticket. A valid passport is the preferred proof of citizenship. For US citizens, a birth certificate and a photo ID are also acceptable. A voter's registration card is no longer acceptable. A visa is not required. US immigration officials will want to see proof of US citizenship on your return. See the State Department website for details at http://travel.state.gov/bahamas.html.

If you're disabled, or traveling with someone who is disabled, make all your arrangements well in advance. Be sure that you let everyone involved know the nature of the disability so that accommodations and facilities can be arranged to meet your needs. On the whole, you'll find most hotels, tour operators, and other facilities are well equipped to handle the needs of disabled visitors.
