The camp is literally a haven:
You can be whoever you like,
you can make it what you want it to be,
you can drink / smoke / party,
whilst learning one of the most fascinating subject to exist / being in a play / hearing awesome lectures,
if you're a guy you will most likely form a very guyish bond and enjoy what it's like to be in a group like that,
It's literally 7am-12am (2+ if you have translations:P) for two weeks of amazing experiences.
And a sub-note: people have such amazing manners and are so friendly whilst you're there, leaving (for me at least, up in the north) you'll be sad at how people aren't usually like this. The teaching staff are usually banterous and generally awesome, too. I can't go this year but it is something that you should do for the greek itself and the extra-life itself. But you get both. It's seriously awesome.
