I spent every morning at the Mandolay Beach! The wave pool was a lot of fun and the lazy river was so relaxing! The waiters come around to all the chairs so I'm not sure what more the paid chairs ($50.00) offered....
I wish they opened earlier than 8:00am because the sun is out and hit around 7:00am or earlier.... I bought a $6.00 water one of the days! I didn't forget to bring my own next time! The drinks cost about the same as everywhere else in Vegas and just as delicious.
The overall experience was very nice. Lots of places to eat; a convenience store with anything you forgot and clean bathrooms. Everything was well kept and everyone was friendly!
