Kristy, Mary Anne, Stacey, Claudia, and Dawn are the luckiest babysitters in the world. This summer, they’re going on the greatest trip ever: a plane ride to Florida, a boat trip around the Bahamas, and then three days of fun—in Disney World.

Of course, they have a million adventures. Claudia gets notes from a mysterious “secret admirer.” Kristy, Mary Anne, and Stacey make some unusual new friends. Dawn has her first real romance. And they still have time for what they like best of all—babysitting!
