For Patti's birthday, the Sleepover Friends are off to the city! Although Kate works out every detail of their visit (of course), nothing goes as planned. Because as the girls are boarding a bus, they get separated! Patti and Lauren are stuck with no money, and-even worse, Lauren thinks-no lunch. Meanwhile, Kate and Stephanie find that everywhere they go, people mistake Kate for the star of a local show, which gets pretty annoying after a while. And then the girls are caught in a thunderstorm! But with romance in the air, what starts out as Patti's worst birthday may turn out to be the best!
