Suggestions for free/inexpensive sights to see with kids:)

[daisy8869]

We will be visiting Tortola and St. Thomas at the end of the month on the NCL Spirit. Our budget is quite limited and we have one member with some mobility issues- she can walk fine but not long distances (over 1/2 mile without frequent breaks). My five year old son will be with us as well. I would love suggestions for things to walk to and see or places with a relatively inexpensive bus/taxi fare (ideally, I'd like to spend less than $50 on our tour at each place for four people). I don't want to miss the opportunity of visiting these lovely places and not getting off the boat!

 

Thanks!
