What should i do for my 16 birthday?

i was thinking of doing like a kids party with a pinata and a bunch of kids games and get a cartoonist to draw cartoon pictures of everyone. but i am afraid that my friends wont have fun at a party like that. It is going to be at the beginning of the summer and it is going to be an all girls party since the last couple of parties i have had a coed party. around 30 girls. It will be at my house and outside if the weather is nice. What do you think? what are some other party ideas?
