My husband and I will also be on this sailing! I have only been to Bermuda on a 4 day before, so really looking forward to this one.
We have things planned, but we will be with a group of others, and someone in our group planned our excursions. You can look for catamaran boat rides, and since staying overnight, you can look for a sunset one. I also know that many people take the public buses/shuttles to the beach.
