I always use Shuttle Park 2 when I go out of town. Why? Once you know how to get there, they take care of you. Go thru the gate and follow the signs to park your car. Get out of car and wait for the shuttle to pick you up. Once you're in the shuttle, grab a complimentary bottle of water. Sit back, relax, and you'll be at the main terminal in 7-8 minutes. Reverse the process on the way back - you get the picture. They have web coupons on their website and you can get a discount for parking a week at a time.
