Don't get lost in that airport. As I"m sure you know its enormous and has its own "tornado center". Few years back we were there to meet relatives that live in Denver. We got off the 1st train -or bus-and waited by the Caribou Coffee. Hours went by and finally a text came in "where the hell are you". We told them and they said we were idiots because we then had to get on another train to go the "main" lobby where another Caribou Coffee place was. I still don't know who the "idiots" were-they or us.
