Sweet 16!!!I NEED HELP!! PLEASE!!!

Hi! I need Help! My birthday`s not until April but my brother(he`s paying 4 my whole sweet 16 cuz my familys budget is really tight..but he`s spending up to around $5,000...i guess) and I are planning now and saving. But we have no idea what 2 do it on....I mean we want 2 do something different. We already know who we`re inviting and where its gonna be and what we`re gonna do..but NJ`s a pretty boring state..thats why we`re hosting it in Bucks County,Pa @ my aunt`s house..ANYWAY...we need ALOT of help on a theme and games and stuff like that...If you have any ideas or info that can help us we`d really appreciate it.
