I would think they crowds will be moderate next week, of course it's anybody's guess!
ESPN the Weekend (at MGM) is over on the 5th...
Local spring break starts on the 10th - 17th....

Magic Kingdom
You can usually find some characters right in Town Square when you enter the park - last week it was Gideon, Pinocchio, Gepetto, Goofy, Max, Suzy and Perla, Robin Hood, Friar Tuck, Little John, Prince.... John(?), Pluto, Baloo and King Louie (I think). They are pretty much out there all day, taking short breaks.
In Adventureland - across from POC - we found Wendy and Peter Pan, Captain Hook and Mr. Smee.
Fantasyland - near Teacups - we found Tweedledee and Tweedledum and White Rabbit
Toontown - Country Fair - three lines - Pooh and Friends, "Classic Disney" and Princesses - we had Jasmine, Snow White and Princess Aurora (even though the CM told us Cinderella was in there)
MGM
Al's Toy Barn - Buzz, Woody, Jessie and a Green Army Man (woman

)
Power Rangers - you need to check the schedule for these - they come out back near Lights, Motor, Action - usually 4 at a time - families start to line up early
Sorcerer Mickey and Donald Duck are near Who Want's to be a Millionaire - and some characters from a Playhouse Disney show -- Jo Jo or something?
AK
We saw a couple out front - they vary, also Camp Mickey-Minnie and Rafiki's Planet Watch.... - I am sure I'm missing something here.
EPCOT - we got the Princesses at Akerhaus Princess Breakfast, and they have the Character Connection which is great - the characters are inside, very orderly lines, with Photo pass Photographers.
EPCOT World Showcase is one place we need to spend some time looking for characters.
