Have you been to a weight loss resort/fat camp?

I feel like my weight is getting out of control, and I don't know where to start to get my life on track. I was thinking of going to one of those weight loss resorts where they make you work out a bunch and make your meals for you. I'd be willing to save money for it if I knew it would be effective. Do you think it's a good idea for me? If you've gone to one of these places, did you enjoy it and was it effective?
