Need 18th Birthday Ideas!!

Ok, so my parents feel guilty about not throwing me a huge sweet 16 and are throwing me a big 18th bday party. They want to invite my friends and family. So that means no drinking or anything fun. How do i make my party not suck with my family there? PLEASE, i need ideas!!! i dont want to have a lame and boring party!
