Leah,
I made my first trip just this week. It's overwhelming if you look online but when you get there it's not so bad. The signs and directions are great. Everyone we dealt with was very helpful and polite. I have a horrible phobia for new places and i could even follow the signs. Believe me, you'll be pleasantly suprised. The shuttle drops you off at the entrance right by the elevator and the information desk. We drove but walked through that area. They were very good about announcing all the different shuttles, making sure everyone had the right one. I hope you find your answers! I'm glad you keep looking for a solution, it's not the easiest choice but don't give up!
Best of luck,
Vicky
