We had a pre-opening ADR at BBB last week. We were let in early and were free to take pics on Main Street as usual.
As we finished up at BBB (I hadn't noticed the time) and were getting ready to leave, the CM let mob was passing through the tunnel. I literally held DD to me in the doorway afraid that she would be trampled!
There did seem to be quite a bit of jostling as the pack approached the carousel and were led into the line. We let the dust settle before venturing out. We asked one of the CMs stationed in front of the carousel
(no one is allowed on the right side of the carousel until much later in the afternoon) how long they estimated the wait to be.
She said 4.5 hours-at 9:10 am.
We had quite a nice time in New Fantasyland that morning, but once the SDMT is in the mix I imagine it will only get crazier.
