St. Johns, Disney Cruise, or an all inclusive somewhere. I would like to go somewhere secluded but within proximity of some fun things to do. St. Johns is great for seclusion, and you can hop a ferry over to St. Thomas whenever you want to shop, sightsee, etc. St. Johns is two-thirds national park land and great for hiking, etc. The snorkeling is terrific too.
Sandals is a little pricey.
All-inclusives come in all price ranges. You tend to get what you pay for. The more expensive ones tend to offer a choice of dining options, and more sports activities as part of the price. As far as I know, there are no all-inclusive resorts on St. Johns, but there are packages that include almost everything. The Poconos are in Pennsylvania.
