I think the complaint to my concierge might have opened up things a bit for Saturday night at the Reno Hyatt Place, at least my concierge later talked to them and "availability improved". She booked me but I had her cancel it because I had already booked somewhere else and wasn't happy.

They shouldn't use the word "Guaranteed" when anytime they have more bookings than they expect (extreme demand) they can just deny globalists. I know it has worked for some (I've seen it when trying to book properties before).
