Village at St. James only has 2 BR from my understanding. It is actually attached to a hotel from what I'm told, somewhat like some of the
DVC resorts. The II book lists hotel units and 2 BR units but my guess is DVC won't do the hotel unit and I doubt they'd want it in this situation. For all of your criteria and through II, I think only maybe Playa Linda, Marriott Ocean Club and maybe La Cabana will meet their needs, all Aruba. Maybe the Hyatt PR would also do but I'm not sure about beach. The Westin St. John's, Royals Cancun, Grand Caymanian and Royal Reef (both Cayman's) will meet the quality but not necessaily the Casino. I don't think there's a casino on St. John but could be wrong.
For non DVC-II trading, I'd add Costa Linda (Aruba) and Atlantis (Bahama's). Other non II resorts of quality but I don't think have a casino include Windjammer (St. Lucia), Club Ortanique (former Ciboney, Jamaica) and Sapphire Beach (St. Maarten).
I would not put the 2 St. Maarten resorts on your list that are on the II-DVC exchange listing.
I'd suggest you do this. Go to TUG and join at $15 for year one. Go in to the Caribbean site and read the reviews on the resorts above and any that interest you. Then put in two separate requests through DVC. One for a 1 BR at the resorts you decide on and a second for resorts with only 2 BR like Antigua. In the mean time contact companies like Dial an Exchange, Donita's, San Francisco Exchange, Trading Places and Platinum interchange and discuss with them what you want. Sometimes units are available a full 2 years out and some of these do request first. Also post a request on TUG for a direct exchange to the ones that interest you and contact any members listed on the direct exchange that own what you might want and discuss with them.
I've heard mixed reviews of Antigua but it does interest me also. Decide what's most important and I'd suspect beach and resort quality are it. If this is the case, I'd look closely at the resorts listed above. Ciboney is mandatory all inclusive but that might be good for a honeymoon. I'd put Aruba, Harborside and Cancun at the top personally followed closely by Antigua, Caymans and St. John.
