We ended up getting a free ticket and a BOGO deal via myvegas and paid $20 for the 3 tickets total. Had I paid regular price on all 3 it wouldn't have been worth it. It was a nice place to take the kids so they can see and learn and even touch some fishes. We were there about an hour just going room to room. The staff was friendly and they were good about answering questions in the touch rooms. They take a few pictures of you when you walk in and they are pricey but we ended up buying one of the good ones. They let you select from different backgrounds. You also get a deal when you buy more than one.
