The OP made a point of saying that her DH doesn't want a split stay. Since I'm no fan of split stays myself, I understand. I want to know that I've got a room to go back to after I've checked in and have a room assignment. And since I unpack after I check in, I'd have to repack and unpack again. No thanks.
I keep seeing this thread in my in-box and my main reaction to it is this: OP, if money is not really a consideration, even though of course nearly anyone would be happy to have $1,000 extra, then you should stay where you want to stay. Period. Forget everything else. Even if you're going to be spending all your time at DAK--just an example--you should still stay at the Poly if that's where you want to stay, where you'd be happiest, and you can afford it. Why not? It's your trip.
