The Hyatt is on the main concourse level or upper level. Baggage claim for all
airlines is one level below, accessible by elevators, escalators or stairs. Next level down is for shuttle service. I would not consider it a far walk, but then again I run 4 miles a day!
The main terminal is rectangular. One long side downstairs is the A baggage claim. The other long side downstairs is the B baggage claim. The Hyatt is at one end upstairs.
