I am going to the Island Seas Resort in September. It will be my first time visiting Grand Bahama. I am trying to figure out a few things. Is it cost effective to rent a car for the week or is it better to shuttle/cab it? Also what are some of the must do/see attractions on the island? We are not trying to break the bank on this vacation since it is kind of a last minute getaway and we are returning to 3 weddings in September. Any suggestions will be appreciated.
