You realize your sisters are “just all opinion” as well. Epcot doesn’t need to become another Magic Kingdom, plus it’s already filled with plenty of family rides.
You’re enjoyment or the kids enjoyment of them is highly subjective.
We spent a lot of our day getting our passport stamped at the country and watching the great shows. Rides are not the only form of entertainment at a theme park. Especially not Epcot.
Magic kingdom is right up the road.
I’m not saying Epcot shouldn’t be renovated and revised, but calling for “more kiddie rides based on IPs” isn’t going to win you over in some groups.
