We flew through Minneapolis when we traveled to Mexico and stayed there for a night. We used Hema's work points to get a hotel close to the airport (they stole Hema's Real Madrid scarf, the only thing we got in Spain..) We made friends with the hotel shuttle driver and he drove us to the Mall of America. We explored for about 2 hours and saw the Lego store, the Peeps store, and I got to try Johnny Rockets for the first time.
Minneapolis airport has enough iPads for everyone to use, for free. What? That's crazy.
