I had always read about it but never tried it. Friends go annually,so I jumped in and joined them. My only regret is that I didn't do it sooner. I enjoyed the classes; they made accommodations for my eating habits; rooms were clean and easy to live in; overall I enjoyed it.
Be advised that when you arrive in the morning for a full day, go prepared to not have your room or luggage with you. Just dress for your first class and you won't even notice.
