In Ochie all of the Sandals are $75 /pp from 10-6pm which includes drinks(alcoholic and non), meals, & use of all water sports. Sunset Beach Resort is $45 /pp, but does not include anything but use of facility. It is not an all-inclusive. Not worth it to do daypass and a shore excursion(unless you are spurging ) b/c even if you do an early one you are usually not back in until close to noon or 1 pm ship time. They are a close taxi ride from ship's tender. Hope this helps.

Wow - Fantastic itinerary. We have more experience with the western routes for resorts.
Last time we were in St Thomas, we took a cab to Meghan's Bay, Orient Beach in St Martins and the Boatyard in Barbados. In Jamaica and Cozumel, I emailed several resorts I found online to see if they offered day passes. That may be a route you might try.
