Not much available for St. John. The Westin is it, I've read some mixed reviews though it sounds nice overall. I don't think it's on the
DVC list unless it's been added recently. For Antigua, only one of the DVC list and it sounds nice as well. I'd also consider Aruba, Cancun, St. Marteen and Puerto Rico where there are nice resorts. Air fare will be an issue to any but less to Cancun and PR than the others.
