MGM Grand Lions - one of my favorite experiences in Vegas was holding a lion cub, Nugget, at the MGM Grand. If you love animals, especially big cats, well worth standing in line and the price of admission for a few minutes to do this!
-The Lion Habitat at MGM Grand Free MGM Grand has a fun lion habitat set up where guests can see lions eat, play and (mostly) sleep. The habitat is open daily from 11-7 but the best time to go is during feeding time so make sure to check the schedule. You can also pay to have your picture taken with a lion cub.
