My family is planning a two week vacation to St. John the end of november. We will be camping at either Cinnamin Bay or Mayo campgrounds. We want to do alot of snorkeling and beach lounging but would like to rent a vehicle for part of the time to explore the island . Because of the expense we will not be able to rent a car for the entire trip. Will it be very difficult for us ( our children are 10, 14 & 15 )to be without a rental car for 5 or 6 days? Are there enough good beaches and snorkel spots within walking distance of those campgrounds to keep us busy for say 5 or 6 days? Or would the buses be a good option? Any advice on how we could make this trip more affordable would be GREATLY appreciated!
