I would like to think that at a resort like these the AC would be working! Probably too well!

It sounds like eight at best. I'll take a room, rather than drive up and back all the time. If enough people come that we need the room, I'll stay at home.

So, the question is three or four rooms, I guess.
It sounds like three for sure, with the fourth one still iffy.

I think Marked may know soon, which could tip things.
