Plan to arrive around 30 minutes early to get through security and find your seat
The shows start a couple minutes before the time on the ticket so if you arrive at the scheduled time you'll miss the first 15 minutes because they won't let you in at certain points in the show
30 minutes before
Arrive at 6pm for sure. As stated by Dan and Joe you need time to get in and find your seat.
