Trying to plan our day in Nassau. We plan on spending lots of money on Castaway Cay to do all that is offered there, so we want to "take it easy" in Nassau. Question is, how does the public beach in nassau compare to the Blue Lagoon excursion? We don't want to spend alot of money on an excursion to Blue Lagoon Beach if the public beach is comparable. I've heard great things about Blue Lagoon, though, and don't want to regret missing it. HELP! All input appreciated greatly!! Sue
