14th Birthday Party Ideas for Girls?

My birthday is in February. I'm turning 14 and I don't know what I should do for a party. I was thinking of having my closest 14 friends (boys and girls) and do something together. I'd rather not have a party at my house because it's small and I need help for an idea. Also my older sister is turning 16 in February too and she's having a sweet sixteen so I'm not gonna be able to do something too expensive. I really want to do something this year since I didn't do anything last year, but I need help on knowing what I should do.
