They are all about the up charge. I'm a local so I got a 20% discount but it was not worth it plus they charged me an extra $5 for an iPod I never used! I just looked at my receipt this morning and was disappointed to find that they charged me for the an iPod I never got.
When we first got to this attraction we didn't realize it was only about the Avenger's. We decided to give it a go anyways. You can use your phone for the interactive parts but it will drain 50% of whatever phone you use with the app. So instead of using your phone you can rent an iPod for $5. We rented ONE, but got zero use out of it. I thought it was one of those talking devices that tell you about each station. The guy at the counter was really vague. The app/iPod you make a profile by filling out information and taking a picture of yourself. After that you get a bunch of multiple choice questions. You can use their device to take pictures, but at the end they charge you for those pictures.
They do let you talk as many pictures as you want while you are there. I suggest you bring your own camera. It really isn't for adults unless you are really, REALLY into the Avengers. Tickets were 34.99 per adult with a 20% local ID discount and $5 rental fee for iPod.
I do not think it was worth the money. Maybe if they gave away a picture at the end it would make it a little better. They were charging $20 for one picture. I am really pissed they charged me for a device I never got... If you do decide to see this attraction please remember to check your receipt!
