Free attractions are always the best!
You only see a couple of lions sleeping and playing around, but when you see them for free and take lots of pictures of them, up-close, you know its one of the best experiences you can enjoy at Vegas. I was looking for some friends over the casino and could not help to stop and look at these beautiful creatures. The trainers were playing with them and inevitably you feel like a kid again, mesmerized by their actions and playfulness. Its a must see for the kid in you (or your kids)
