The Kid-at-Heart travels to play. While others are weighing whether something is too touristy or too silly, this type is already in line, grinning. Delight is the whole metric — the water slide, the ridiculous themed café, the street performer, the souvenir so tacky it loops all the way back around to perfect. And their joy is contagious; they tend to make everyone around them have more fun than they'd planned to.
The trips that satisfy this type say yes to the fun stuff without embarrassment: theme parks and festivals, quirky roadside attractions, animal encounters, arcades and scavenger hunts and whatever looks like an adventure. They're not too cool for the obvious delights — they know the obvious delights are obvious for a reason. Spontaneity is half of it; the best moments tend to be the ones nobody scheduled.
What's worth protecting is permission to be playful and an itinerary loose enough to chase whatever looks fun. Over-serious, over-planned days smother the very thing this type came for. They'll know the trip worked by how hard they laughed and how many times the day surprised them into pure, uncomplicated joy.
