The real test/proof will be whether rates drop a couple of nights before the stay. I noticed higher rates back in early May/June for the month of June and July. But a couple days before my check in date, and on the actual date of check in, the rates dropped. I presume someone is making the decision to hold out for as long as possible; a last minute cheaply sold room is still revenue compared to an unsold room. It's not like these guys are on the same level as Bellagio or even the majority of the Strip casinos.

Whether this holds true for August, who knows. I'm sure weather and seasonality has something to do with it. There's also the fact the property may be getting sufficient business from conventions/business bookings to keep the rates at triple digits. There's just no way to know, unless one actually has access to the numbers.
