Going back out to vegas in august, normally we have been staying at the aria, last 2 years, however for some reason the rio offered 4 nights for free have no idea why haven't stayed their in quite some time. and I am no longer a diamond player. wife thought we ought to try it out last time we were there we had a corner room with a kitchen,living room, large bedroom and two bathrooms. should we go with this compt or stay at the aria any comments has the rio improved that much or are they hard up for guest. as a side note are there any compts out there for red rock, how does one go about getting one, thought we might try them out.
