The Riv houses our group in multiple places in the hotel, so I don't think we have a specific tower. I think I have had rooms in three different towers for the last three conventions. Of course the best room was the in the tower with the elevators right next to the Splashbar! Wooooooooooooo!
P.S. Great picture of Ron and (one of his) B.A.M.s. But the best picture of that shotgirl was taken by Bryan Jimison!
