Just as a FWIW...we had a 1:30 lunch. The food was SO good, and we wanted to take our time, just relax. We sat, we talked, we ate...
And then we noticed that on the voucher it said to check in half an hour BEFORE 3:15 for preferred seating.
Since it was already rapidly approaching 2:30, this was problematic.
We actually arrived at the normal line area well after we were supposed to be at the preferred line (by the way, seems if you go across the bridge to the right it will swing you out in the right direction...going through the EE area puts you at the normal entrance...at least that's how it worked for us!). They said it was too late, but that there was plenty of normal seats.
The normal seats were up higher and of course further away from the stage, but there were performers and action that happened up *behind* the preferred section. We ended up liking the normal section better than how we would have liked the preferred. (same situation as for Aladdin at DLR's DCA...preferred is in the "orchestra" section, and for a show with elements happening all around and above you, you're missing out if you're all the way down there)
