Stacey's so excited! She's invited her friends from the Baby-sitters Club down to New York City for a long weekend. It's going to be perfect-a party and a sleepover Friday night, a big baby-sitting job on Saturday, and lots of sightseeing on Sunday. But what a mistake! The Baby-sitters are way out of place in the big city. Mary Anne sounds like a walking guide book; Dawn's afraid of everything; Kristy can't keep her mouth shut; and Claudia's jealous of Stacey's friends. Does this mean Stacey can't be the Baby-sitters' friend anymore? Will the Baby-sitters Club fall apart?
