I discovered that I can get a free room (pay the room tax or whatever only) at the Rio when I decided to see what logging on to my Total Rewards card account would do. So, $50 for two nights (rather than Priceline's $41 a night!). AND I have secured tickets for Penn and Teller's show there. AND I'm still looking at what else to do since I am NOT going to casino hop all of Las Vegas in a couple of days! In fact, I don't intend to do much hopping, though we will certainly visit a few.
