17th Birthday Party Ideas?

I was looking for some ideas for my 17th birthday party. I live in Portugal, in a small town, so big parties with cool themes are out of my options. I was thinking about inviting some friends, probably just girls, but I want to do something different than just go to the movies or have a sleepover. If I do it that way, my boyfriend wouldn't be there, it would be boring for him.

So, I could invite those girls and some other friends (boys and girls) from school and we can just choose some place to hang out or go to movies (but, here's the problem, same old tradition again). What advices or ideas could you give me? Thank you!
