Taking a shuttle bus is the worst possible thing to do, IMHO.

Take a look at the map below (it's not the greatest, but it'll give you a general idea of the layout):

The shuttles go in a sort of circle from A to C to F to D to B (then back around), so the flow is opposite to what you need (plus they are always jam-packed - the drivers don't leave until people are squeezed into conditions that most sardines would object to)


It's easy to walk - looking at the map, at the extreme right of 2D (near Door 3, but you stay inside), you would walk down the corridor (part of the way is via handy moving sidewalks). Walk right on past the Sheraton hotel and the train stations, down another walkway, and you will be at the entrance to 2F.

There are plenty of rolling carts for your luggage and the walkways are nice and wide to accomodate the carts. 10-15 minutes, no problem
