No. If you have an t.v., there are private sites within a half hour. Otherwise, there is a motel 6 in King of Prussia that would probably be the cheapest thing around.
You not only aren't allowed to Camp there but people are not supposed to be there at night time. Don't try to stealth Camp, it's well patrolled. There are a number of really nice Pennsylvania state parks where you can camp including French Creek Park which is only a half hour west of Valley Forge
No campsite.
People come there to spend the day... But not sure whether you can camp there..
