first of all, as I understand it, these will available to book at 75 days out for us since we're 1st timers, correct? Are the chances pretty high that they'll be all booked by then? Secondly, we are not huge beach people. And we're only doing the 3 nt. cruise so won't waste a whole day at the beach. I anticipate we'll be off the boat as early as possible (it says 8:30 on the itinerary - is that pretty accurate?) and probably back on by noon. I can't really justify that kind of money for 3 hours. I haven't found any options for half day rentals, so are there perhaps any underground cabana-share groups that someone can fill me in on? It seems like a brilliant idea but I haven't seen any talk of it so I thought maybe it went the way of the Photopass Share groups.
