The kids think they’re going to Grandma’s or the water park, but…surprise! They’re actually going to Disney!
There are plenty of variations on this, but the gist is the same: The kids know a trip is in the works, because their bags are packed and they’re piled into the family truckster. But the destination is revealed en route either in the car, or at the airport. You can drop clues along the way with Disney videos or travel games, or play it straight and let it hit them as they drive under the familiar welcoming arch.
Avoid the flop: Be careful with this one if your kids truly love the faux destination. If they’ve been dying to see Grandma, they’re going to be pretty bummed to know they won’t be seeing her after all (unless she’s coming with you on the trip). Instead of setting up the trip with a different fun destination, try using something less appealing to kids (“We’re going to go hang out at a boring hotel while Dad attends his conference on sprocket recovery systems.”). That way, the real destination will knock their socks off.
