Hi Jo Anna,
Getting to meet your favorite characters is an essential part of a Disney vacation for many guests. They can be found in specific locations throughout the parks. When you arrive at a Disney park, you'll find two guides. One is a map detailing all of the attractions, and another is a daily schedule of parades, entertainment and special character meeting times.
Another way to meet characters is by dining at one of the many restaurants in Walt Disney World that features character dining. At these restaurants, characters visit each table for photos and to sign autographs. It's a fun way to get some one on one time with some popular characters without having to stand in line.

HERE to be directed to a link of all Walt Disney World restaurants. On the left hand side of the page you'll see a menu titled DINING EXPERIENCE. Select CHARACTER DINING. Every restaurant features different characters, so I recommend reading the descriptions to find one that your family will enjoy.
Unfortunately, you won't be able to find characters just walking around throughout the resorts.
