If you are going to Las Vegas, do not book it through US Air Vacations. We stayed at Planet Hollywood (which I do not recommend at all either!) and our hotel room never got below 80 degrees!
After complaining, the hotel showed us 2 other rooms and both were also very warm. They employees even agreed they were warm. Our shower had mold and mildew in it and the shower head was corroded with lime and calcium deposits. Planet Hollywood said they would love to refund us 100% but since we booked it through US Air vacations, US Air would have to do the refund.
I called US Air Vacations about it and they pretty much told me "too bad." They said the room has already been paid for and there is nothing they can do about it.
Hopefully they'll go out of business too!
