I'd wait an hour for ExEv no question, if there were no FastPasses.
We started doing Disney when there were no FastPasses & had several hour long waits "back in the day" While we tried to avoid those waits whenever possible, we still did them if it was something we wanted to ride & the lines showed no signs of clearing. In fact, I remember when Test Track first when on FP. We were actually disappointed at missing the queu (it used to go in the side door & skip the queue show completely)
Now that we are used to Fast Passes, we have been spoiled into not waiting much more than 20 minutes for anything. I wouldn't say that I would never wait more than 20 minutes, tho. Sometimes you just wait. That's life in the World. Even the waiting can be fun.
