Going to a local roller skating or ice skating rink. If they have a room you can rent out, maybe do that too.
A themed movie night. Pick a certain type of movie and watch a bunch. Have the girls dress up like a character or from the time period. My friends and I did a Harry Potter party last year for Halloween. We all dressed up like a different character and ate pizza, drank orange soda (pumpkin juice), and had candy corn and other stuff. We watched our two favorite HP movies. It was a lot of fun.
Laser Quest.
Funny thing is, I'm trying to come up with my 18th birthday party right now. I'm probally going to go to the local ice rink or do a photo/video scavenger hunt since all my friend's can drive. But I'm not sure if that would work for your daughter unless you and a few parents (depending on how many girls and how many teams) would be willing to drive them around. Half the fun of the scavenger hunt is going to be getting lost I think hahah =)
