I actually can't tell you the name of it, because I don't know it. It's one of those early 90s (maybe late 80s?) movies where kids run riot because of cruddy parenting and then find their inner responsibility and everything works out excellently. Like Camp Nowhere, but minus Doc Brown. I saw it on tv when I was small, it was one of those rainy day child-pleasers. I keep meaning to look it out again but as yet.. I have not!
