I'm visiting Vegas in December and I'm looking for a place to swim while I'm there. I know that it will be freezing so I'm looking for heated or indoor pools. I swim to exercise so I need a lap swimming pool. Anyone knows which hotel offers this? I'll be staying at Mandalay Bay but I can go to any hotels that have this (as long as they allow me to use with reasonable prices). If this is not available on the strip, what are the options near the strip? UNLV? Thank you very much.
