I've never been to any amusement park, aside from those nomad luna park ones, when i was little.
A buddy of mine went to Disneyland Paris once, and i was seething (i was always the poor kid in the group, so i was seething often), but then never got the appeal, past that age (10y old or so).
The only reason i could see someone older than 10 or 12 going, is if you're a teenager bringing their date there or an adult bring their kids.
Not even trying to shame now, just genuinely don't understand what's enjoyable about Mickey Mouse and shit as an adult.
Rollercoasters and Ferris Wheels, fair enough, but you don't need to go to DW for those.
