Replying to Windells worth it?

Every year I see advertisments and videos from the windells summer camp, and i finally decided to check out the website. Everything there looks sick and definitely it seems like a good time. BUT, the price is not cheap, and I don't have a lot of money to spend on fun stuff like this. SO, is the week really worth it? Is it possible to learn a lot in that short of time? Are there any deals or offers they make? And are there any less expensive summer camps?
