When people say not to miss this you should listen to them! This is easily the best free show in Vegas (just a little better than the child street performers in old Vegas!).
It became the running joke because the first time we came to see the fountain show it was cancelled because of high winds.
The second time we went it was 1pm and a voice came on and said "The first show will start at 3pm". Come on!
Third time was the charm, we'll kinda. We got there 10 minutes until 11 pm and he show had already started so we saw the last two minutes and let me tell you the show as beautiful!
Minus two starts for the inconsistency and plus one for the actual show being great!
