One suggestion if you do get assigned a room in the farther-out buildings, especially 7 & 8, is to ignore the directional signs in the resort and choose your own path.
For our first visit which was just a few months ago, we had a 2nd floor room in Building 7 on the wing toward the lake. After a day or two, we realized the fastest way to get to the food court was to totally ignore the signs along the pathway that point you way around and to the foosball courtyard. Instead, we walked along the backside of Building 10 to the other end. MUCH faster because you don't have to wind your way through the courtyard theming, and dodge people coming in the other direction along the sometimes-narrow pathways. (Which is why Building 10 is our first choice for location when we go back down in June)
Just draw a straight line between your room and the food court, or your room and the bus stops, and follow the paved pathways that keep you close to that line.
(This is also good advice for most Disney resorts... The signs in Coronado Springs don't always point out the shortest route)
