We were there last week 9th-12th and here are the characters I remember....
Disneyland
Mickey - Mickey's house in toontown & also on Main st, in front of the pumpkin decorations near the Mad Hatter store.
Minnie - Minnie's house in toontown and then sometimes we saw here on Main St with Mickey. But, we rarely saw her alone last week on Main St.
Goofy - Main Street near the Mad Hatter and Lincoln movie area. Also, saw Max with him once. Also, he was walking around Toontown, near Roger Rabbit's ride.
Pluto - Main Street, again near Mad Hatter & Lincoln movie. Seemed, if Goofy was out, Pluto wasn't and vice versa.
Mary & Bert - Outside Plaza Inn, they were walking into their backstage area, but we got lucky and got to meet them.
Alice & Mad Hatter - Outside Plaza Inn too, actually met them the same time we met Mary & Bert
Princesses - Near Small World...they changed 2 times while we were in line, which was about an hour. We met Tiana, Aurora, and Princess Minnie. But we did see Ariel, Belle, Cinderella, & Snow White.
Woody - Big Thunder Ranch, but we saw him during the Halloween Party. Not sure if he was there during the day or just during the party.
Eeyore, Tigger, and Pooh - Saw them at Critter Country. From what we heard, apparently the characters were always there, changing every few minutes, but seemed to be continuously having a character. We met Eeyore and Pooh at the Halloween Party and then met Tigger and Pooh during the daytime. I cried when I met Tigger...38 years old and I cried over Tigger!!! I'm a dork.
Pinocchio - He was out on Main Street, but we never got to meet him, always got to him a little too late. But he was there 2 of the 4 days we were there.
Jack Sparrow - Across from Pirates was a pier & boat, he was here meeting everyone. Funny guy, truly could have passed as Johnny Depp's brother!
California Adventure
Not sure what the streets/sections are called, so I hope when I describe the areas, they make sense.
Mickey - Saw him on the main street near all the shopping. I know it's not called Main Street, but not sure what it's called either. Never met him at CA, again, always too late.
Minnie - Found her by the plane by Soarin over California
Pluto & Goofy - Found them over by the shops, near the circle that has the Walt and Mickey statue. Usually if Goofy was there, Pluto wasn't & vice versa, but we got lucky, just before Goofy left, Pluto came out and we got to meet both of them at once!
Donald - Only place we saw him was here at CA. Go passed the Duffy store and the Little Mermaid restaurant, heading to the Paradise Pier area. There was a gazebo at the end of the street. There's were Donald was the entire time.
Jesse & Woody- In between California Screamin & Toy Story there was a white pier area with a roof...this is where we met Jesse. We did see Woody, but the line was too long to meet him here.
Sulley - end of the shopping street, as if you're going towards Tower of Terror area. We met him on the corner. Loved him, cause he made noises as we took our picture. Kept making us laugh.
I hope this helped. I know these characters can change from day to day and location to location, but these are the ones we met last week and the areas we met them out. I hope this helps everyone!
Happy Disney Day!

Also how often do they change who is signing? I am trying to make autograph books for my three boys.
