Denmark - Tivoli

Perhaps the happiest place in the world, this Danish theme park is where fairy tales come alive and so do your fears of unregulated roller coasters from the 1800s. It’s a magical wonderland where joy is measured in overpriced cotton candy, and the real thrill is seeing your wallet disappear faster than a Tivoli light show. The happiness is contagious, though—it has to be, because once you're inside, there's no turning back.
