Went to Disney Paris for 2 days with 11 & 15 year old.
Everyone said before they were too old & that it’s mainly for young kids that want to be princesses etc but actually it was brilliant and the total opposite.
And loads & loads of older European kids there. We did both parks over 2 days & did everything from the buzz light year ride to thunder mountain & marvel and they loved all of it!
I actually think it’s way better with older kids as they really get it and there’s tons for them to do.
So if you are thinking about it with older kids, do it! It’s great!
