Airy and bright under the tent roof
The iconic peaked roof lets in tons of light and the underground trains to the concourses are quick.
It sits well outside the city, so budget real time for the trip in and out.
There's something calming about the big open architecture here, especially on a sunny Colorado day. Getting between the main hall and the concourses is fast thanks to the underground trains. Just remember it's a long way from downtown, so plan your ground transport accordingly.
