I was pretty underwhelmed by this experience. I have been exposed to several alternative building technologies and ideas. I found this attraction to be self-promoting ("OUR design is THE way to achieve a sustainable life") vs. ideology promoting (there are other ways to live, and here's one!). With that in mind, $7 ($7.50 with tax!) to walk through a small building reading placards, watching a promotional video and slideshow about how they do what they do, and having the opportunity to buy lots of overpriced books and knick-knacks was unreasonable.
If you've never seen something like this, certainly worth having a look. If nothing else the loud-architecture will entertain you (not all alternative, off-grid homes are this gaudy). However, for me it ranks at the very bottom of all my alternative technology experiences.
