Very nice. I agree that most Caribbean islands don't have much to offer in terms of sites etc.. However, we spent a week in Barbados in April and had a great time. I am not a beach person and we found quite a bit to do there and could've used another day or so. I also found the people to be some of the friendliest and nicest we've ever met.
If you get a chance, I'd recommend you going back for a longer visit!
