For the price, I do not know if it is worth it, not much to see inside.
We arrived right after they opened and waited in line for probably 15-20 mins.
When we left the line was seriously over 100 people and almost stretched all the way to the casino carpet!! Those people probably waited over an hour for a 20 minute long overpriced exhibit. If you really want to take your family, arrive right when they open! It is no way worth waiting in a line like that.
The pricing of items in the gift shop surprised me though they are fairly priced. The photos however are a rip off unless you purchase them in a package with a ticket.
