I come from a Disney mad family - my parents went to the original one in California and to Florida before me and my sister were born, and I’ve been to both in America plus Disneyland Paris multiple times (lost count!) as a child and adult
Disneyland Paris is a bit less overwhelming, I was asked my opinion on which Disney to strike first and I would recommend, for example if child wanted to go but you were not so sure, go for Disneyland Paris. It’s smaller so not as overwhelming as Orlando and only needs a 2 or 3 days to complete (slightly different matter in the height of summer!
Different strokes for different folks
It’s not just the rides, it’s the atmosphere, particularly in America where the staff go out of their way to bend over backwards to help you (Europeans haven’t quite got this mastered)
Due to my Disney family, we always had the films on video, Disney books and story tapes etc. But I grew up liking theme parks in general and love a good roller coaster now.
I think Disney would appeal if you are not so into thrill rides (as they’re aren’t so many)
I was one of only a couple I knew who had been to Disney at primary school. More had been when I was at secondary school. Out of my group Uni friends only a couple of us had been. Majority of my adult friends still haven’t been close to it. Don’t plan to take their children there.
Meanwhile I’m looking at going alone !!!! Tho what I really want is to see the Harry Potter stuff at Orlando, but you know, whilst I’m there.....
So no, I don’t think your children will be left out. To be honest I’ve worked with children for a decade and only ever had a handful really talk about the place.
