That's also my fear with what would essentially be a no-show as well. So getting to a resort/FW just to check in for the throwaway room may be the mitigating factor in whether this is just too much of a pain in the butt

I'm certainly hoping someone gives it a shot before our trip to let us know. I have every intention of calling CRO to ask, but we all know their answers have been, um, inconsistent in the past so I'm not holding my breath on anything they say.
A family could genuinely be planning to camp for one night just as a special treat for the kids during an off-site visit but if it's pouring that day, it takes the fun out of it and I wouldn't stand outside pitching my tent in the pouring rain just for one "fun" night and would probably change my mind and stay in the hotel. If that was the first night and thereby forfeits MB/FP+ privileges already booked for the duration of tickets I'd be pretty upset so want to make 100% sure of what's going on.
