I just got back from Staying at the Rio and it was a GREAT experience. I know its not one of the nicest, or flashiest hotels in Vegas, but it was clean, the people were nice the rooms are HUGE. Generally the food was great and we received great service. I know some of my Co-Workers rooms were pretty shady-so I suggest checkign out your room as soon as you check in and calling if there are any issues. You can't beat the price though i've stayed at the Excalibur in Vegas before becuse its Cheap but it looks and feels cheap the Rio did not- I would stay there again.
