I arrived at 4:30am on Saturday morning with a friend. We were each getting 2 tickets and could go to either show. We were 11/12 in the line and by the time we got to the box office, only 2 seperate SRO tickets were left for the evening, so we got 4 together for the matinee. I feel like 4am is your best bet to guarantee a spot.
The tour is COMPLETELY different from the scary trailer we saw a few months ago. They have the complete set from the Equity tour, all the costumes, Dianne Paulus' associate directed the tour and original choreographer Chett Walker choreographed the show. Should be very close to what we saw in 2013 and on the road.
