Summery movies/ones where they go to camp, like Meat?

I really like feel good summer movies, especially set at camp. Meat is a good one, since I like watching films that are less recent. And the Parent Trap is good, and the remake. Anyone have any suggestions? Anything would be appreaciated, thanks a lot. By the way, I'm a 17 year old girl that's really into 80's/90's movies at the moment if that helps? :)
