So working in theme parks gives me headcanons about little kid modern AUs. Hiccup would be the toddler who wants to ride ALL THE ROLLER COASTERS but gets spooked on Haunted Mansion. Astrid would ride everything but have to muscle through the coasters because she doesn't like drops (until she gets used to them). Snotlout would scream at characters like Mickey and Goofy but chat up the princesses. Fishlegs would ride Small World 20 times in a row. And the twins would have to be on leashes.
