I love it how people say this place is a MUST SEE, when it's more like hope and pray you see something. I've been to Vegas 3 times and I got to see a Lion one time out of all of my trips and he looked extremely bored. Also it's just an akward exhibit. Yes, MGM Grand has a giant one out front, but this is a little bit away from the casino floor and the sports book. Just could be a better presentation.
If you haven't made it around to checking it out yet, don't bother.
