What are some good ideas for partys?

Im 13 turning 14 and ive had some pretty cool partys the last 2 years and i want to have one ALL out party before my sweet 16 (kinda a lil teaser). Ive had a HUGE hotel party and a beach party and have no idea what to do for this one! oh and by the way just to let you know im a spoiled brat and my dad has been gone for 10 years so he has a lot of making up too do(:
