Efteling to UKR is such a stark comparison. Granted, one has been building up for 75 years, and European parks seem to offer better value on average than their US counterparts, so it's not really fair.
But it is an interesting cultural comparison. I love how much being at Efteling feels like being at a really nice public park. Everything in the fairytale forest is so cool, and it's even better because it's swathed in greenery. They make a real effort to be ecologically minded, and it shows.
Meanwhile, UKR sprouted in sprawl of north Dallas. I guess we shouldn't be surprised there's so much concrete.
