Okay this is only a free attraction if you are walking through the casino i guess. Every few minutes the one of the drink servers hops up on stages scattered through out the casino and performs a short song or dance. The ones that do it are called BevErtainers and its a little weird and quicky but its kind of fun. It kind of reminds me of Johnny Rockets where the servers perform a little show ever so often. Its free and quirky and does catch you off guard if you weren’t expecting it. It happens 24 hours a day and is an added bonus if you visiting the Rio.
