Came here today for the first time since my first visit from 14 years ago. There are a total of 10 dolphins now, with a baby that is about 9 months old. They rotate the tigers and lions throughout the day in the viewing areas so the animals can stretch their legs for the guests and still have some quiet time in the 9 acres behind the scenes. On this day we were lucky and got to meet Siegfried himself and he actually took the time to meet every guest that wanted a chance to say hi. He is a very polite person and I can tell he misses the stage and loves to interact with people. It's a definite place to check out if you are at the Mirage.
