4 of us went on 12/24. I don't have a detailed breakdown of what we did, but here's a summary...
Led into TSL about 7:10-7:15. SDD was not up. No word on when it would be.
Rode Aliens twice before 7:30.
Rode TSM 3x. That long exit is KILLER when you're trying to maximize rides.
When we came out of TSM the third time, SDD was up. Wait time said 25 minutes; felt like 20.
At that point, it was 8:40. My parents stayed for one more SDD. Son and I left for RnR/TOT.
I overheard that we got an anytime FP because SDD was down. When I tried to use it at Star Tours at 10:15, they said it expired at 10 am. They let us FP Star Tours anyway, so no harm no foul.
Overall, the crowd was about what I was expecting. I've done the MK EMM before, but not this one. The crowds seemed comparable. If I have one quibble, I think the anytime FP should have lasted past 10 am (and loaded into your
MDE account). I enjoyed it and would do it again.
