HG, if you went during a holiday period, you might change your mind.
I've gone during busy times (summer, weekends, and Thanksgiving week of '09.) NONE of those times compared to the crowds a month ago when the Christmas season began.
I have NEVER been fearful of losing my children at DLR until November 12. The crowds were so think and massive that I did lose my DD7 for a moment because our hands were torn apart by the crowds.
Collecting FP's was not the easy task that it usually is in the summer (and that's a busy time). I was in the park with my two young DD's (no other adults with us) and we debated getting a FP at rope drop or heading to Peter Pan. We chose PP (with a 20 min wait right at rope drop), and I didn't get my 1st FP (for Space) until 8:40 am. That was a mistake because the return time was already 12:30. It completely threw my entire FP collection schedule off. Normally I can get another FP in 40 min or so. That day I had to wait the entire 2 hours, and that NEVER happens to me.
Your touring strategies definitely are true, and I follow them every trip. But on this recent trip I learned that early FP's (and I mean first thing) are crucial. I also learned that lines build everywhere in the park within the first 2 hours of the day.
OP, don't let a "long" line (or at least a line longer than you are used to waiting in) at 10 am keep you from going on that ride. That line will never be shorter that day.
You will NOT get done what you are used to doing in the park compared to ANY other day during the year. But I do agree you will enjoy the decorations and the festive atmosphere.
I wouldn't say I had fun on my recent trip, but I went in not expecting the major crowds. (I expected it to be very crowded but not crazy!) If you go in with the right expectations, a plan, and positive attitude, you can have a great time.
Also consider the holiday tour. We took in on that busy day, and it made the day for us.
