If you want your first trip to be a happy one I suggest keeping it simple. Choose one or two places to go ahead of time. Use the internet
to find the closest marina to where you want to go or get a book that lists marina details. There are many books
that info about the Abacos. Check West Marine
or other marine
book stores. Once you have a plan call them before you leave Florida to make sure you can clear customs
there. If not they can tell you where to go first. I just found this with a simple search. The Abacos | The Official Site of The Bahamas
In general...Even if you don't have a plan marinas all over the world operate pretty much the same. You can pull in unannounced and just go to the fuel
dock and tell them you want to stay for a few hours or longer. They will direct you. One thing to consider though is popular places like say the Abacos might be completely booked so calling ahead would allow you to reserve a spot. Be safe have fun!!
