13th birthday party ideas..

Hi,
My DD turns 13 in July & would LOVE to have a party. She's already come up a disco in our garage, i thought this was a good idea until i really thought about it - we live in the country & it would be absoluty freezing but we'd need to nearly empty out everything in there (where the hell would we put it all??!! thats why its all in there!) as she would like to have at least 20-30 kids there. (boys included of course!) Im not too sure i really want to be responsible for that many children at once - esp at that age. Im guessing the party would be on a saturday night from about 6pm-10pm? Does that seem fair?
Any ideas? (PLEASE!!)
I really would like to do anything but this disco party!!

Thanks!

6-10 does seem like a fair time for a disco to me. I bet shes so excited. My eldest dd just turned 13 and she had a group of girlfriends over for the night and they all went shopping, to the movies and out for dinner..ended up being a great night. When we have had party parties at home, with a larger group of 20 its worked really well having other help, like granma or something, at least with the cooking and help with supervising. With that many children, there are always a few you dont know wanting to push the boundaries a bit..especially at 13. Have fun!!!!!!!!
