13TH BIRTHDAY IDEAS

My 13th birthday is in 18 days and I don`t know what to do! I need to do something cool that is good for about 17 teen girls. I was going to do a mall scavenger hunt but that wont work. I want to (blank `cause you are coming up with ideas) and then go back to my house for a sleep over. I only have about 2 hours for (blank) because I have to have my party after school on a friday and still have time for dinner. Any party ideas from parties that you or daughter or girl that you know went to or had? Anything helps! Thanks!
