My kids and husband were terribly disappointed "Sum of All Thrills" was not open during our trip in July. I tried to warn them, but they needed to see for themselves. They would have rather designed and rode their own coasters than do either Mission : Space or Test Track. It was definitely one of the last pieces of "edutainment" (physics).
I must be a terrible "Disney mom," because I expect (note present tense) my kids to learn stuff in Epcot. Over the years, we have done the piggy bank, the velcro, what state grows what food, UL testing labs, the Pumba safety and even the crazy healthy "superhero" thing. Some days, little kids just need an air-conditioned place to climb a fire truck. And sometimes, even Mom learns something like apparently NJ uses all of their tomatoes (maybe makes Campbell's tomato soup with them), but exports berries.
One of the best surprises of our last trip a malfunction on Living with the Land. The slower ride through the greenhouse gave us a better opportunity to see everything. Then, after we were evacuated from the boat, we escorted through the remainder of the ride. My kids asked a lot of questions from a very knowledgeable CM named Laura. We got a mini behind the seeds tour.
