I think if you used Divi not as an AI and were not expecting much out of the rooms (again, maybe they are better on the inside than they look on the outside) and it is a great deal, then go for it. Wonder if you can get a deal that includes a breakfast as I imagine you will be out exploring for lunch and dinner. STX does have some hiking but not on par with Dominica (never have been but have heard it is very nice for that). There is much to do and see in STX and it is a relatively big island compared to most in the Caribbean. If you decide to go, let me know and I can give you a list of things you might like to do. If you go to Dominica would love to hear a trip report!
