I'm sorry that your family is disappointed about missing the butterfly garden. My son and I really enjoy that sort of thing too, but to tell you the truth, I found the waterfall/butterfly day of the itinerary to be the least interesting part of the trip. It was fun, but it was not very unique. We've been to several butterfly gardens in the US that are just as good or better. The rest of the trip was great. I hope you enjoy it as much as we did!
