francie_iowa,
I feel like you can throw the strategies out the window! Of course, this "slower" season has become more popular as the years pass, but DH and I have gone to WDW together 2 times, and both were during September (mid). We have had no problems waiting in lines, except on Saturday's at MK. Of course, i remember also waiting for Test Track in a 30 min line, and I remember that Jungle Cruise had a longer line last year too. Splash Mountain had a longer line as well.
My point is this, long to me is not "typical" long. We are used to walking onto rides, or waiting no more than 10 mins. Spoiled?yes...eating it up? Most definitely!
The parks do get more busy as the day progresses, so keep that in mind. DH and I usually get up early and are at the designated park before it opens, or at opening. This time though, I have already stated that we will sleep in a few more mornings.
As for Fantasmic, I am sorry to say that you still need to get there early. That is one show that can't be missed, and everyone knows it. Last time, I had fun sitting on the bench playing with my Tinkerbell light up toy! We also try to do it as one of the last nights. Always brings tears to my eyes...
