No personal experience, but a few of my friends did Camp America after university and absolutely loved the experience. They met so many good friends out there. One now works as a 'soccer' coach in the US, one works as a teacher in Miami and another works in education in Canada. All happily married with kids.
Judging by their experiences - there were a lot of young english students working out in the camps as 'counsellers' at the time (just over 10 years ago) so they didn't get home sick and felt very welcomed and supported by the employers.
