So the higher floors usually have more parking . The garage is not very busy on the upper floors plus after the fourth things calm down. Try 7th floor if you don't want to be on the roof.
There should be ample'general' parking on the south end of the garage by the international airlines if you don't mind the extra walk. There are lit up LED signs at each helix ramp that shows the number of slots open. The north end by Alaska Airlines is always full.
