As I've spoken about in the past, nostalgia is an extremely powerful emotion. It can make us make questionable purchasing decisions but it can also make for some very interesting innovations. One of these innovations is the summer camp for adults.
Just like during those wonderful years of adolescence, adults can now sign up for summer camp. These camps can be based on various themes (e.g. singles-only, celebration-oriented, etc.) or can just be an alternative form of vacationing. Either way, adult summer camps are driven by nostalgia. The social dynamics developed during such adventures mimic those of our childhood and thus add a new layer of satisfcation - in addition to being away from the hustle and bustle of daily life.
I say that this concept should be expanded. If we can revisit the years of early adolescence then why not the teenage years or the early 20's? Both High School Camp and College Camp seem like the obvious extensions of this service. Who wouldn't want to go back to High School or College for a week, but this time, without the need to pass tests?
