Haha I was thinking the same thing. I stay on that end of town fairly often and actually like that area but the traffic can be a pain. I would guess that when this resort opens From your room to the Magic Kingdom Parking Lot will be a solid 20-30 minutes if nto more depending on traffic.
I live in the area and if you just take the back road behind Chick Fil A you only have to go through one stoplight and can be to Animal Kingdom in 5 minutes. But, you are correct if you are traveling during rush hour or early in the morning when the parks are opening it will take longer.
Just curious since you know the area, how much of a walk would that be?
It not the distance as much as there is no sidewalk most of the way and once you enter Disney property (by Animal Kingdom) their is no pedestrian connection to the park entrance. I have seen people walking it but I wouldn't want to do it.
