To be clear, I'm not discounting your personal experience at all (and I don't think anyone else is, either). In fact, all I'm doing is expressing my own personal "data" point.
We're cool.
My memory of World Showcase as a child was spending most of the time in shops (love Norway for the Trolls for this reason) and being forced to eat souerkraut. It had cool looking buildings but Future World did too and those cool looking buildings actually had stuff for me to do inside them.
I've always loved American Adventure because it hits a similar note that SSE does but really have no fond childhood memories of Morocco, UK, Germany, Italy, and somwhere-in-Africa-that-isn't-an-unstable-country-land for instance. What I remember most about the circle-vision in Canada was not being allowed to sit.
I feel this area was built with a mind more to an adult audience, originally, and that most of the family-friendly features came in the form of the live entertainment you could catch in France, or say the magician/wax guy in Japan, China, etc. More than half of those pavilions today still only feature sit-down restaurants and alcohol and shopping as their "attraction".
I'm glad that it sparked a sense of wonder for you that carried over into adult life and helped shape your own personal future. I always thought the settings in places like Morroco and Germany and Italy were cool (and not to dig too much on Canada's movie but Canada, too), I'd have just liked them more if there had been something in them for
me to do the way it appeared there was for adults.
There were no "special" drinks for me and kid-cot didn't come along until later - not that I think kindergarten craft projects are suitable substitutes for attractions intended to hold the interest of children along side adults.
That said, I still think it's the wrong place for Frozen but I can accept what's happening in Paris and a carosel in the UK would be a welcome sight to me, too. If Germany and Japan had gotten what they were originally supposed to, I'd have probably had a much better opinion of this area as a six year old back in the day with my Four Seasons Pass, too.
