I am looking at some of the St. Thomas, St. Marrten excursions and I am wondering if a 2 year old is allowed. I know that the snorkeling, sailing or hiking, biking type adventures are not for someone so young, but like the Sapphire beach day trip is basicly just transportaion to and from the beach with a lunch buffet. The prices listed are for ages 10 and up and a child price for ages 3-9. So does this mean that a 2 year old is free or a 2 year old is not allowd? Thank you, for any input!
