I've never traveled to the Bahamas with pets, but be sure to check out the regulations. I found the below Web site and excerpt in a quick Google search. My vet prescribed acepromazine for sedation. On my most recent trip, I tried going without, and they actually did better. I wouldn't sedate her unless you think she's going to be destructive or loud. And for such a short flight, it's hardly worth it. But definitely ask your vet.

To bring a dog into the Bahamas requires an import permit obtainable from the Department of Agriculture, phone (242) 325-7502. To obtain a permit, send your name, address, phone number, age of dog, sex of dog, breed of dog and $10 U.S. dollars. For an extra $5 they will fax the import permit to you. Mail the information and money to The Department of Agriculture, PO Box N3028, Nassau, Bahamas. It can take up to 2 months for the permit, so plan ahead! Additionally, if you are coming from the US or Canada, you will need a veterinary health certificate issued 48 hours before embarking and a valid certificate of rabies vaccination for either the one year rabies vaccine (given to the animal at least one month before arrival, and not more than 10 months before arrival), or the three year rabies vaccine (given to the animal at least one month before arrival, and not more than 34 months before arrival).

Here's another site I found with a blogger's firsthand experience, but it was dated 2002:
