If push comes to shove take the "B" Parking Lot shuttle and walk. The "G" bus gets you a little bit closer but they don't start running till 6am. The taxi is $17.50 min fare no matter where you go. So if you're in a rush or can expense it, take a cab; if you got time you can take the bus and walk. The walk is about 1 mile and only takes 15-20 minutes at a normal pace.
