We were ther Nov. 30th-Dec. 4th. We would ride it and then get a fast pass for later. We saw a wait of a hour on that Sat. The rest of the time didn't seem bad. The longest we waited was 15-20 minutes. On our last day, a Sunday, we rode early and were able to ride it twice without getting off the ride
Get there early and get your FP's. I was in the park yesterday around 3 and the FP's were gone and the line was posted at 60 minutes. If you wait until 10:30-11ish the line drastically reduces in size.
