The first time we rode, we went at 4:45pm on Saturday. Wait time posted was 3 hours. Actual time waiting was 2 hours, 10 minutes. It started raining while we were in line, though, so that might have caused delays?
On Monday, we got in the queue at 1:15pm. Posted wait was 2 hours, 30 minutes (150 minutes). Actual total time in the line was 50 minutes.
The ride, itself, is brilliant! As noted, we rode twice (so everyone in our party could experience both the motorcycle and the sidecar) and, if possible, I think I had more fun the second time because I knew what was coming, where to look, and could relax, look around, and experience more. Everyone in my family made comments that seemed to indicate that they felt the same.
I actually had more fun in the sidecar, as I felt like it took the pressure off or something - I dunno, it was just more relaxing fun. From his grin, I think my husband enjoyed the motorcycle more.
I don't have good things to say about the queue. Single rider was not open either time. I believe they must have closed it at some point, because there were definitely single riders in line when we got to the front. The ride was truly brilliant, so it's possible that I could change my mind - but I told my family that I disliked the queue so much that I did not plan on riding again until they either had Single rider open, or Express. It's not the wait that bothered me - it was all the walking. And, unlike Forbidden Journey or Gringotts, I found the queue to be downright boring and, in many cases, stifling. I'm not claustrophobic, but a person who is will not be able to make it through this queue. Also - both times I went through I had very loud talkers in the party ahead or behind me. So I could not hear what was being said in the last area at all. If there was non-visual theming going on that you had to be able to hear to enjoy, I missed it.
Again, I won't spoil it for anyone, but the ride itself is well thought out and brilliant. Plan to ride it at least twice during your trip.
