If you have never been to Vegas this is one of the things you must see on your visit. I have been several times, and it is still awe inspiring watching the blasts of water and streams dance along to the music. The shows are well choreographed and the music choices vary. The show is completely free and the show happens every 30 minutes M-F from 3:00pm to 7:00pm and every 15 minutes from 7:00pm to 12:00am.\nSaturday and Sunday is every 30 minutes from 12:00pm to 7:00pm and every 15 minutes from 7:00pm to 12:00am. This is one of the best free shows you will ever see in your life and is not to be missed. Make sure you make time to be there when the fountains start and you will be in for a treat.
