Definitely need to ride this multiple times to get a real feel for it, and figure out where in the world I"m supposed to be shooting. We had quite a long time in line to figure it out, about 60 mins ,but once I started shooting, I had no idea what I was doing .It was still fun, but I would need much more practice. We went on a pretty busy Sunday on Columbus Day weekend, really just to do this ride, as this was going to be my husband's only day at Universal, and he wanted to try it. I would maybe wait 20-30 mins, or only ride w/ express. I do love the Despicable Me franchise, and the last part of the queue is cute. but neither my son nor I chose to try and ride again later in the week. My husband and son managed to sync their blasters, but mine never did. App wouldn't load/save the info. I had qutie a few app issues the whole trip though....was very frustrating, but personally I like the idea of doing more on the app/phone, mobile order, etc (WHEN it works!!) I LOVE mobile order at Disney, and use it as often as possible, I did make sure to get physical tickets for HHN and express, just to not have to deal w the phone/app issues.
Hopefully can try it again on a future trip, as long as the wait is not too bad.
