Deb, I'm glad you posted the question because I was thinking of posting one myself. I need to hear from people with experiences and I hope you get some more replies.
It's a huge amount of money for us. Part of me says, no amount of money is too much if this truly helps our daughter. The other part of me thinks, what if it doesn't work or pushes her back instead of giving our daughter the little nudge forward we think she needs? We could have just taken a Disney trip for the family instead!
I've been mostly looking into SUWS in Idaho because it's not too far from us and I was referred to it by a therapist. However, hearing a great support for it is motivating me to look into Outward Bound more as well. I'll keep researching and let you know if I find a great site for reviews or something I find really helpful. Good luck!
