As you see on the map there are many islands to choose from. If you want a floating hotel to move you from place to place choose the cruise with one of many cruise lines like Holland America, Carnival, Princess, Celebrity, ...
If you however decide to go on your own you might want to start from U.S. Virgin Islands. You will fly to Puerto Rico, stay there for its beaches and rum factory, or fly to Saint Thomas where you can see the picturesque capital Charlotte Amalie and take a short ferry ride to San John. You can also fly from Puerto Rico to Saint Croix. All of those islands have beautiful beaches and water with salt levels that allow you to float easily.
If you like all inclusive resorts try Jamaica, they have several of them to choose from, some of them adults only.
There are also Dutch islands like Aruba and Curacao with beautiful white sand beaches, French Martinique and Guadeloupe or British Jamaica, Barbados, St. Lucia.
