That's a good question. I waited an hour today. I'd say that for the queue and the ride combined (because the queue really was that impressive, in my opinion) I would wait 2 hours on a summer day. I fully expected to wait 3+ today and got very lucky with an hour. But I would say the attraction as a whole is worth a 2 hour wait. This is coming from someone with an annual pass, and I can always come back. It would also depend on the day for me (when I show up, how long I stay, etc).
