Wow, our experience was completely calm.
This is Florida, btw- I had some friends at MGM at opening. There was maybe only 5 people with them at the hat.
I arrived at DtD at around 11 AM. Walked right up and got some. They would break open a new "pack" of 10 if you asked. There were usually one or two Maximus pins per pack. I saw one or two other traders I recognized, but we all came in far enough part that we didn't have to line up.
Between the 3 of us, we got 2 Maximus (one w/ Rapunzel, and one with him and Flynn staring each other down), and most of the other were Gondola pics, but really *excellent* shots of it...
I have no idea how the other Parks were, or how DtD was at opening, but when I came back to get my car at 7 PM, there were still 7 or so left at DtD, but the scenes were pretty crappy.
Everyone was nice, and plenty of good scenes. Maybe we just avoided the bad spots or people or something...
