I'm a GW fan. It's very quiet and, while you may have a walk inside the GW, it is literally a one minute walk to the tower building once you leave the GW. Once you enter the tower, you are on the ground floor, so no elevators to the buses or to start the MK walk. I think it's the best of both worlds because you can also experience the tower 4th floor concourse when you'd like. If you want the theme park or Bay Lake view, the GW will not give you that experience.
