We didn't do the Universal Express pass when we were there. I might consider it when both kids are older and want to ride more big rides. Charlie ride Flight of the Hippogriff a few times (we stood in the line and it was not too bad); Marty and Alex waited in a long line for the ride in the castle and rode it once; Alex was a bit freaked out and didn't want to do it again so I didn't ride it. We were able to walk onto that twin dragon coaster a few times with a minimal wait early in the day. I would say for us, especially if we were doing both parks in one day at that time of year again, I would give the express pass serious consideration. Or maybe next time we would just plan to spend two days.
