An oldie but a goodie and I always make sure to check this out every time I am in Vegas, especially if I have newbies with me.
Although the show is great any time of day I really enjoy the nighttime shows better. The show runs every 30 minutes at night and it is set to different music with different water shows every time so you can see it more than once if you want to,
Get there early to get a spot in front of the hotel, streetside because in my opinion that is the best view. If you are off to the sides you won't get the full effect and be able to see the different levels of water dance from there.
This is a show that is not to be missed if you are a first timer to Vegas or have seen it a bunch of times like me!
