Must not go on the same Septembers because in Dec when I go, its usually pretty quiet. this last yr i remember even low times of 20minutes for TSM and other rides.
I cannot compare when you were there, only compare our visits. We went this same week in December 2009, also end of August 2008, end of September 2007. Of the three, the December 2009 crowds were the highest. (Remember they added FD last year at this time.) This is not saying they were terrible mind you, we rarely waited more than 10 minutes for anything. But there were definitely a lot more people around. The AM we did TSM we got on no problem, but did it at rope drop. The night we did the Osborne lights was quite honestly the busiest I've ever seen DHS, though this WAS a Sunday night with EMH. This is the only time I've ever left a park because it was too crowded.
We also were there the end of April this year, and I thought THAT was less crowded than the December trip. Again, I am not saying it was bad (unless we are talking by Saturday the 19th - that was crowded!). I'm comparing non-empirically the crowds as we walk through the park, and there were more people around in December than any of those other trips.
I am not saying this to discourage the OP - I would
highly recommend that week as a week to go to enjoy the Christmas festivities. The reason we went was that we could go on the Saturday (the 19th last year, the 18th this year) and see all the Christmas stuff from
MVMCP at MK for no extra charge - this is the day they start running the parade, the stage shows, and the fireworks as the REGULAR shows. This is also why it was crowded, but it saved us spending $200 on MVMCP, and we got to see most of the same things.
