To add my experience: My party visited last week, dedicating 2 of our days to the Studios to ensure we rode. We arrived at 6am for 7am opening both days. Inside the park around 6:30am and the boarding groups opened on time at 7am. First day we got group 88 and rode around 2pm. Ride made 167 groups that day! Second day we received backup group 132 and did not get called, as the ride had a terrible day making it only to group 94. I wasn’t as distraught as many other guests by knowing what I was getting myself into, but be warned, getting on this ride is not guaranteed. Simple math really. I estimate it cycles 10000 or so guests in its present state, so if the park is slammed with 50 000 guests during holidays, most won’t be riding.
Disney claims that the ride runs 1700/h once fully operational. Even with those numbers, it’s going to take quite a while before standby and FP lines can be manageable enough to open.
I feel lucky to have experienced the ride. The best animatronics I have ever seen, which I prefer to mostly screen based rides.
