It's not as busy as later in the event, but it's still busy.
Last year opening night the regular queue for Myers house was 90 minutes.......WD was longer, can't remember exactly.
We always get EP.......wouldnt do it any other way.
But, if you didn't mind queueing you could do every house in one night. Are you planning to be in the holding area......gives you a good start on regular folks.
