And as a reminder, when you're at the airport, it would behoove you to spend most of your time at terminal D because it has the best food and shopping options.
(As for the ACs, see the recent thread entitled "Which AC at DFW is best?" or something like that. The short version: A for the showers/exercise room, D for everything else.)
