If you were there for early entry last night (Wed), it was nearly a ghost town for about the first 90 minutes. Stranger Things was a walk on. Klownz was about a 10 min wait at 7pm. Us, Pandora, and Corpses were basically walk on as of about 7:30. Holidayz was about 30 min, and after 8pm, lines did go up to average about 40 min--but still pretty low compared to other nights. Left at 9:30 pm after a Jabawookees show (which was still nearly full).
Here's a screen shot I took of the wait times at about 7:15 last night. It said Klownz was 20 min, but we actually waited 10. Really, until about 8:30, the longest line in the park was 20 min for Simpsons.
