We're planning our first cruise with Norwegian and are wondering whether to take the Atlantis Beach Break ($85.00) is the right way to go. Their website indicates that this is a '4 hour' excursion which seems a bit too short to us and it appears that there is a short ferry ride to get to Atlantis. Anyone have any experience with this? The primary issue isn't the money but the amount of time we'll have; we're in port from 8am to 1am (all day and evening), so there doesn't seem to be much of a rush. Any thoughts.
