I visited in August 2016, when the Frozen show was still fairly new. I went by myself and chose not to do one of the dining packages. I got in the FastPass line as early as I could, and I was able to get an amazing seat! I got a center seat in the second row of the seats behind the aisle break in the theatre. Excellent view of everything - including the amazing staircase! I'm glad I didn't opt for the dining package, but again I was by myself and was happy to wait in line for the hour before the show. If I had kiddos, that hour long wait might not have been as okay.
Have fun!! I really enjoyed the show, I hop you do too!!
