I stayed at the Rio last night. Almost everything was great. Had the typical suite. My issues we're unrelated to the customer's service, which was great.
1) You have rooms that large and don't have a central lighting fixure. Had to go around the room and turn on all four lamps to see anything.
2) The shuttle service to the strip is great, but they don't allow lugguge, so I had to pay for an Uber. That would be a nice courtesy. Granted, I made the dumb decision to stay off the strip, so I guess I derve it.
