E is for: Extra Magic Hours = Extra Crowded
And all the people who don't know better (like me the first time) pour into the parks for Extra Magic Hours. Combine that with only some of the attractions being open, and it's not so magical. Then add in the non-extra-magical guests after regular park opening, and ay yi yi.
Have any of you had better experience with Disney's Extra Magic Hours?
