The 4 Queens is the 4 Queens. It's not Cesar's Palace, it's not MGM Grand. It's a really cheap place to stay while in Vegas. You'll have a clean room with great service and all the employees will treat you well. If you pay more than $75 a night you're paying far too much - I think my rate was $35 a night on a May weekend. Compare that to $200+ for the lower-end Strip casino/hotels.
Make sure you get a room high up if you're in the north tower - the Fremont light show can disturb you otherwise.
