I have read and expereinced that the later MM (when the park opens at 10, so MM is at 9) are a lot more crowded and that was the schedule yesterday. It makes sense I think. It is a lot tougher for people to make a 7AM MM than a 9AM one. So, if they are early, I don't think it would be so crowded. My kids aren't interested in Space or Star Tours, but those are open. Star Tours had about a 25 minutes posted wait at 9:40ish when we were in line for Buzz. We got in line for Autopia right before 10:00 when it opened and the wait was 20 minutes. They were not offering FP for it yesterday morning, but I can't say if they were over the weekend.
