April can be a great month for that trip. As long as the weather settles down.
Personally I'd blow off the keys and spend the extra time in the Bahamas.
As to paperwork, get your US customs sticker, make sure everyone going over has a passport and try to get everyone enrolled in the Local Boater program.
