Check the Greyine Tours. They are always fabulous! They have all day tours or several hours. I always take them when I'm in a large city. Worth every penny.

Thanks so much for the wonderful suggestions. Makes me wish we were staying longer; so it sounds like we could make another trip at another time.

There's a lazy river at the MGM Grand, I think. That sounds promising!

We just got home fro Las Vegas. We went to Hoover Dam, and the Mob Museum. Also walked on Fremont Street....that is an experience.

We’ve done city tours in big cities & never been disappointed. Possibly book at your hotel.
