We have member points for both. I have read reviews on both. The Westin got a lot of very mixed reviews mainly due to hotel in need of major overhaul and usually a lot of children (nothing against children...just that we are leaving ours at home for our anniversay :-)). Marriott seemed to get better reviews.
I've read if you stay on St Thomas you must do a day trip to St John for the beaches/snorkeling. I guess that's why we are considering St John. Other than that (and not to be taken for granted...the magnificant beauty) is there much to do on the island? Is there more to do at St. Thomas since it is larger?
We are very adventurous and love to hike, jetski, snorkel, sail, sightsee and enjoy nightlife including dancing. Unfortunately, my husband usually has enough of the beach by early afternoon; sunburned and bored if there is no surf to bodysurf.
We will definately get a car for either island we choose so we can go exploring.
Any input would be greatly appreciated. Thanks
