Have to admit, although we have done many Caribbean cruises we have never had a "sleep over". Knowing cruise lines as I do and their tendency to want to "own" their customers, I wonder what excursions they would offer? I can't think of much in Phillipsburg but that is not my side of town. There are lots of entertainment options in the airport area and of course, Grand Case but almost any place I can think of would be overwhelmed with a bus load and it would be the odd cruiser that would know the ropes well enough to go on their own?
