Sounds fun! I've camped since I was four years old. It's great. Even if you don't have time to set it up, at least check to make sure your tent has all the parts it is supposed to -- stakes, poles, and such. I agree tents have quirks, and learning what they are in the dark isn't fun. But with a group, you will have lots of help.

You may not need an area light if you are camping at the high school, but you should take a flashlight or headlight.

Have fun!
