My biggest concern right now is that most of the offerings appear to wind down around 10pm… but the event itself runs until 2am.
Forbidden Journey, Mario Kart, and Jurassic World close early for nightly maintenance. Hogwarts Always had its last show at 11:30. The Yoshis leave at midnight, and I assume other meet and greets are similar. I’m not sure when Back to the Future closed.
So, from my count, only the following things were running after midnight… Dungeons and Dragons, Star Trek, the Dreamworks thing, Secret Life of Pets, Despicable Me, Mummy, and Hippogriff.
At the very least, I think they need to have Back to the Future go later. If that isn’t possible due to noise concerns, I think more of the characters need to stay out.
