The wait times in the app were not accurate at all today. Park hours were 10AM to 8:30PM. I arrived at 8:30ish AM and left at about 8:45 PM, riding it 12 times. Other than lunch, a bit of shopping and one ride on Hyperspace Mountain, this was basically all I did today.
The posted wait time hit 60 minutes within 10 minutes of park opening and rose to 70 mid morning. It dropped to 45 around noon before rising back up to 70. Late afternoon, it fell to 45 and at night, it dropped to 30. These wait times were a bit overstated though since I was waiting closer to 45 minutes when the posted time was 60 and about 10 minutes less for the other posted times. My last ride of the night was about a 10 minute wait.
Assuming the ride continues to have this M-pattern, it would be a good option for rope drop since it does not have Fastpass. The rides to the left side of the park typically don't open at rope drop so there aren't any other good non-Fastpass rides to rope drop. If you have energy, you could get in a couple rides between We Love Mickey and Paint the Night. However, at night, a lot of the ride vehicles were getting out of sync so that the last room was basically unplayable and many other parts had you staring at a blank wall. Hopefully, this will be ironed out in the future.
From now through June, Magic Access Members can receive one Priority Admission pass per day for this ride at the right side before entering the park. They ran out at about 1PM today. I predict that waits will be better on weekdays but once summer hits, the ride may have even worse waits than today.
