Allie's back with a brand-new set of rules!

Allie plans on having the best weekend ever when she finds out Erica's sister Missy is in the regional Twirltacular baton competition until Allie's mom announces that she has to go to Brittany Hauser's birthday party instead. But Allie doesn't even like Brittany Hauser, nor does she want to go to a party with Brittany and all her snobby friends. But when Allie finds out Brittany's party includes taking a stretch limo to Glitterati, the store of the girls' dreams, and spending the night at a deluxe hotel suite, she decides maybe Brittany's not so bad after all.
