We are taking a cruise to freeport and nassau.  We are wondering about the ports.  First we decided to snorkel at Paradise Cove in Freeport.  The Nassau port we are not sure what to do.  We have figured out booking excursions with Carnival is marked up like 200%.  When we went to Cozumel, the excursion for a beach/park with Carnival was 80 a person.  We caught a cab, and paid 5 bucks for the cab ride and 20 bucks a person for the same thing Carnival had to offer.  Any suggestions for Nassau like this?  We are not afraid to get in a cab or bus and go somewhere fun.
