Thanks everyone for your posts. It is in fact a GTY SV, so I think it's the scenario where we'd end up in an open IV, whether that be prime, concierge or aqua, so for now my TA and I both agree I'm going to wait on booking and watch to see if a cabin we actually want to select becomes available. This is what I did for our recent Edge sailing in January and it worked out, if not we'll select a different ship and itinerary. Happy Cruising, all!!
