You don’t need a theme park. Kids are easily impressed by bin lorries and pigeons fighting over a chip. Take them to a local park, give them a stick, and you’ve basically saved £200. Pro tip: Bring a flask of tea and pretend you’re on a safari while they hunt for “mystery puddles.”
If you want to look like a superhero, introduce them to geocaching. It’s a real-life treasure hunt using your phone, and it’s free. You’ll walk for miles, they’ll think you’re Indiana Jones, and you’ll all collapse into bed by 7pm. Win-win.
