Unless you're an Avengers super fan save your money.
Don't get me wrong overall it's well done. It's interactive, but they really didn't nail the whole system down. Basically it's confusing in each room if you're supposed to take quizzes or pictures or just read the info in the walls. In the end it doesn't matter you can just walk and enjoy.
That said it's not like they really have that much on display. The Iron Man room is the only one worth anything.
The last part of the tour you are supposed to be shooting at a big huge digital screen as part of your "training" but again it's confusing if you're supposed to try and aim or just hit the button on your device. In the end you feel like 6 strangers standing in a row everyone just touching their screen repeatedly.
Overall I'd say again don't bother unless you really love the Avengers, otherwise it's a big geek fest and waste of money.
