In January, I attempted to check into the Rio very early- I think I got there around 10AM on a Monday. The clerk told me nothing was available but I should leave my bags at the coat check and come back after 1Pm. He said he'd have everything ready for me then and I would have a nice mountain view. I thanked him and gave him $10. As I was walking away, he called me back and told me to hold on a minute. I got a room right away and it turned out to be one of the real suites. - Kitchen, dining room living room, two bathrooms and a jacuzzi.
Thats not the first upgrade I've gotten, nor will it be the last.
