13th Birthday IDEAS!

It`s my 13th Birthday in July and I really need some ideas. Im thinking about inviting between 15 - 25 girls. The thing is, July is in the middle of Winter so that makes it just that little bit harder. I don`t want to go all extravagant but i still want my 13th to be special and a lot of fun. Please help me with some ideas!
