This happened to us on 1/31 as well. 7DMT was down until around 8:50ish. They kept the standby line back until right at 9:00, so we could get a couple quick rides in with very little wait. Then our bands worked for all 3 rides as FP until noon.
It feels like very few people there, I'd say 200 or less is right. Even with one ride down, waits were still practically nonexistent on the other two.
We also got stuck on Peter Pan for several minutes first thing. They gave us 5-person paper anytime any ride FP for that inconvenience as we exited.
Overall, even with the bumps, we liked it and would do it again. We never buy the upsell events because we usually don't see the value for us, but this was a great experience for not much more than a character meal. I was bummed about not doing 7DMT practically empty at first, but my husband liked spreading the rides out better. I think we rode more times that way too. But we have several MK days, so we weren't on a tight schedule for other rides either. We ended up spending the morning riding 7DMT several times in a row, go to our FP, repeat.
I thought the breakfast was great - those chocolate pastries mentioned are pretty awesome. Quite a few options too. We ate about 9:45 am, and they were still keeping the buffet filled and hot. It was a quiet, relaxing meal after rushing around.
It's also nice to see all the CMs relaxed and having a good time. They tended to focus more on interaction when they weren't having to herd a thousand people through a line. When we were walking to Peter Pan first thing, one of the CMs even offered to park our stroller so that we could go ahead and get on the ride.
If they keep this on long term without increasing tickets sold drastically, I can see us doing this on future trips.
