I guess its officially the "quad" now...but I'll review it as the IP since they aren't finished remodeling. Lets just say I got my room for $30 a night for the weekend, so I'll base my review with this in mind...
Good: Great location. Cheap price. Room service was actually pretty good. Fast checkin but long lines (blame that more on the clientele than the staff though)
Bad: Food court blows. So hard to find.
Ugly: Its midwest tourists run amok in Vegas. When I went to the Aria that weekend walking around I couldn't help but think "people here are MUCH MUCH more attractive than at the Imperial Palace".
Overall: I'd stay here if the cost of the room is under $100 a night.
