In Toontown in the Mk there is a meet and greet line in the Toontown hall of fame for princesses. Toontown opens at 10:00 a.m. Be at the rope a few minutes before and go straight to the meet and greet...otherwise you will have a long wait. Here is some info from allearsnet about it....there is a section about the princesses towards the bottom:
ATTRACTION -- Toontown Hall of Fame -- As you approach the Hall of Fame/County Bounty facade, you pass through Cornelius Coot Commons. Be sure to stop and read the dedication plaque, which reminds you that all of Mickey's Toontown Fair is dedicated to that enterprising old farmer, "Cornelius Coot, who turned his corn crop into loot."
Inside, you'll find the County Bounty, which features plush animals and all kinds of Toontown souvenirs, as well as special Toontown Fair "blue ribbon-winners." Beyond the merchandise area, there are three rooms, each with its own line, for private meetings with a variety of Disney characters. You're welcomed by stars from all sorts of favorite Disney animated shorts and classic feature films -- signs will tell you who's currently greeting guests in each room. These characters MAY appear: Storybook Friends - Pooh, Tigger, Piglet and sometimes Eeyore; Famous Pals - Minnie, Goofy, and Pluto; Toon Pals - Donald and Daisy. (All characters are subject to change.)
Meet your favorite Disney princesses in the Princess Room. The Princess Room debuted in early October 2004 to meet the high demand for meet-and-greet opportunities with JUST the princesses.
Princesses are on a rotating schedule, so ask before you wait in line as to which are currently greeting guests. Princesses on the schedule include:
Aurora (aka Sleeping Beauty), Snow White, and Cinderella (and her mice Suzy and Perla). Mary Poppins may also be in the rotation, and other princesses may be added to the schedule.
