It's doubtful you'll be able to beat the bus or light rail system or price. A one-way ticket is $1.75 outside of the 'rush' hours ($2.25 between 6:00-9:00am and 3:00pm - 6:30pm) and ranges from 11 minutes on a bus to 13 minutes on the light rail system.
A Trip Planner is available. There are stops at terminals 1 and 2.
You should easily be able to spend between 2 and 3 hours there.
