Any great ideas for a Sweet 16 party?

My oldest daughter, Fly, will be turning 16 very soon. She wants to have a great party, but is all out of ideas. There will be about 20 guests around her age, and funds are somewhat limited.

Some things about her: She’s a brainiac and mature for her age; she’s into reading, fashion, the internet, and movies; her favorite TV shows include House, Fringe, Gilmore Girls, Planet Earth and some kind of criminal/law show that I’ve forgotten the name of; and she’s currently learning how to drive.

Some of the rejected ideas include: pool party (she’s had many, and is over it), skating, going to DC (transportation issues), just a regular party in a rented place, and a Harry Potter costume deal (she really wanted to do this, but a good friend also wanted to do it, so she’s being the bigger person).

Please give us your most creative ideas to make this birthday really special for her. Thanks!
