We are on the Jan 8 sailing that goes to St. Thomas and Tortola. I researched and booked excursions through Disney on both islands. However, both of those were canceled today. I am unable to book any other Disney excursions for my party of five - no availability. So, can anyone give suggestions for excursions that we can do on our own. My party consists of three older teens, a middle age mom, and a very adventurous grandmother. We were going ziplining and snorkeling, but now would be happy with something easy and perhaps close to the port. We are super disappointed about the cancelations, and would like to find something fun - but I am a little uneasy about doing things on our own. Thanks for help and suggestions!
