Great advice above!

If you want to push the easy button - You may want to consider a day trip over to Water Island. The ferry leaves from Crown Bay. Quiet beach and a great day on the water.

Another option is a family day sail. I know you at a big sailor but the Fury is a 35 year old Morgan Ketch with a great Capt. They do daily as well as private 1/2 and full day sails. Turtles for those who have not seen them.

One thing for sure in STT you want to know the Cruise Ship Schedule. Best day to go to JVD is when there are multiple ships in.

And I hope you have a St John adventure planned for day. You can ferry over and walk from Cruz Bay over the hill on the Lind trail to Honeymoon or Salomon Beach. Honeymoon has a place to grab refreshments. Hit the 3 pm Happy Hours in Cruz Bay and head back to STT at a leisurely pace.

So many things to do in such a short time!
