So funny you would re-post this now. I am actually heading back there next month. We did take the train in Oct 2010, but it was not an enjoyable ride (alot of questionable security guards). When we got off the train and started walking, I did see spot where the Hilton shuttle picks up and drops off at the mall, but thought I could make it on foot. After walking around in circles for more than an hour (with a lot of luggage), I finally walked up to a que'd cab driver and asked him to take me to the Hilton, he just smiled (and laughed) at me and said it was just around the corner, gave me detailed instructions and sent me on my way. Anyway, for the trip next month I will arrange the Hilton to pick us up at the airport to bring us straight to the hotel. Hope you enjoy your trip.
