This is from BradK on another site I visit:
"As you may know, Toontown normally opens an hour after the rest of the park. On the same days as EE (but this event is exclusive of EE, even though the two can be done on the same day), those with passes to Mickey's Toontown Madness get to enter Toontown an hour before it's open to the public.
While the entire land is open and attractions are running, the highlights are that Mickey is immediately available for photo-ops. Around 20 after the hour, there's a parade in which all the citizens of Toontown march down the street and then hold a meeting at City Hall where they first make some family honorary citizens of Toontown (sort of like how
Disneyland selects a family to open the park) and give them some sort of rolled up document which I assume states as much. Then all the guests are announced as being honorary citizens of toontown for the day and are given buttons (i will be posting a photo of the button on my pictures site within the next couple of days).
After the ceremony, all the fab five are available for photo ops as well. And the big pay off is that there's so relatively few people in the area. Whereas Mickey and Minnie's house typically have a queue time approaching 30 minutes each and Gadget's Go Coaster's line gets ridiculously long, everything is pretty much a walk-on and you can knock out the entire area within 40 minutes including the ceremony.
oh, and here's my tip for getting through the ceremony:
there are tables and chairs all around city hall, so you'll find people finding a spot shortly before the ceremony begins. don't follow their lead - sitting at disneyland is for wimps.
the parade comes down along the street and all those people facing city hall are going to miss it, unless they turn around, and even then, they're pretty far from it all.
there's a gazebo in front of city hall (right in the middle too) which (at least in my case) remains near empty and is open on both the sides of city hall and the street where the parade comes down. stake out a spot on the gazebo and when the parade starts, run down to watch it and get close, then go back to the gazebo to watch the ceremony. you have to stand, but the ceremony is only ~15 minutes anyway.
in my photo album, the parade photos were taken in the street and the ceremony photos were taken from the gazebo."
By the way, if you see a family of six, hispanic dad, caucasian mom, three daughters & a son, good chance it's us. We will be there same days as you...
