Sorry I’m just logging back in after returning from Disney yesterday!
We were told by a CM working the 9:00 standby line for Fantasmic, that the 7:30 show had filled up 10 minutes before it started.
We lined up a little before 8:30, were let in about 8:40, and the show never filled up. We could have walked up at 9:00 but we didn’t want to risk it.
Hope this helps someone else!
