Everything went fairly smoothly. We were one of the first groups in line so were seated in the first theatre. In all they opened 6 theatres for the movie. We were in a theatre that seats 300 and it was completely filled.
Luckily they didn't make us stand in line for hours, they allowed people into the theatres to sit and relax (and purchase from the concessions of course).
The movie.... well it was ok. As an adult it probably wouldn't be my top choice on my list. But the girls really enjoyed it and that was what the night was all about anyways.
