Not aware of any that actually have 'passes'...however, if you went to, say Sapphire Beach, no one knows if you're a guest of the reosrt or not, so no one is checking to see if the people in the pool are actually staying there. But, at the Marriott, if you don't have your key or towel card, someone at the swim-up bar might mention something to you. I mean, all places have signs saying that their pool/facilities are for the exclusive use by their guests, but I've not seen much enforcement. If you buy lunch at INDiGO at Magens Point Resort, I knwo that youy can then use their pool. I wonder, though...you are only going to be here for, say, 8 hours...and you wanna spend it at a hotel?!? Why not just stay on ther ship and have the place to yourself? Personally, I'd get out and see some of the island, but, to each their own, right?
