If the band camp is held at your high school, then you will get to go home. But if it's out of town, you probably will sleep there. The same thing happened to me last year when I wasn't expecting to have to go to band camp. But have no worries!! It really isn't that bad, just kind of exhausting. You just get to hang out with your friends and stuff while learning music. You'll probably enjoy it!!
Good luck!! : )
