We went on a rainy day I'm May. Steady rain, no lightning. We arrived about an hour before posted start time. When it came close to the original start time they began making announcements that the show was delayed. About 45 more minutes passed, with more announcements about delays, then they announced Fantasmic would be canceled. Left very wet, and a little frustrated that they didn't cancel the show earlier. On the positive side, we went back 2 days later and loved the show.
