Rode this 9 times on Sunday. Once for our AP preview at 11:30 (wasn’t off the ride until close to 12:30; there was a fairly long wait) and then 8 times for the
D23 event. Got soaked during the thunderstorm that popped up as we waited in the special Harmonious viewing area for the D23 event. Decided not to wait out the rain to watch Harmonious and ended up riding 3 more times before the event ended at 10:30.
It was an incredible experience; we got 5 of the 6 songs during our rides. The only song we never heard was Conga. On ride #5, our Starjumpers rolled backward down one of the hills and the ride shut down for a few minutes. When it started back up, there was no music or lights for the rest of the ride. Never felt any motion sickness and neither did my 60 year old MIL who was with me. I definitely put this at the top of my list of WDW coasters. It was so much fun and I’m really sad that I’ll probably never have a chance to ride it multiple times in a row again.
