We are going on our 2nd DCL next week (Dream on Feb 17-20). Last year, we did the Blue Lagoon Beach Day. It was fun, nice, and easy to do with just me and my 6 yr old daughter at the time. This time, my husband is joining us. The only DCL Port Adventures that interest me are Blue Lagoon Beach Day or Balmoral Island Beach Day. What are some non-DCL adventures we can do at Nassau? I'm nervous about being on our own for transportation. I'm looking for something that is only 3-4.5 hours. I am a Costco Member if there are any options through Costco that you can recommend.
