In 2004, we went to HDDR. I had booked it about 8 months previously. However, Hurricane Charley arrived the same day we did, and shut down the FW area for several days, so we lost our reservation. But, we were able to get a different night. We did end up in the balcony on the side. It really wasn't all that bad. We had a great view of the show, and the performers did come upstairs...not all of them, just one or two.
So, my dd, then 11, loved it so much she asked if she could come back and celebrate her 13th bday there. And that's what we're going to do. We will have 2 moms and our 2 dd's, mine turns 13 the day we have for HDDR, the other turns 13 two days later. I booked it in 2004, for this coming Oct.
From what I can gather, the seating 'may' depend on 1. when you booked 2. when you pick up your tickets 3. when you show up at the podium.
I don't believe it's the podium checkin, since we were the first people there. And we did pick up our tickets the same day as the show, and we did make the reservation about 2 days before. So, it may be a combination of those two things.
