We went to the program with my daughter. Overall we liked it. She did not have any siblings or neighborhood friends at the time, and she was/is very social, so we wanted a regular group of kids to hang out with. We were very interested in Waldorf at the time, too.
However, in the end we just decided it was too expensive for what it was, and we decided against Waldorf for various reasons. Personally, I think it's a "nice to have", but not worth scraping to get the tuition for. Maybe you can arrange a free playgroup that would use a similar "Waldorf-inspired" approach.
