s&k'smom,
We've only stayed in the south wing one time when DS was really little (we have stayed in the north wing about 5 times and the tower 3 times). At that time, we would typically have someone go to the snack bar to pick up french toast sticks (or whatever

) for breakfast while the rest of the family was getting ready. (Now that DS is older, we like to sit down for breakfast at the Concourse Steakhouse --so, it probably wouldn't be as big of a consideration for us, now).
Anyway, my recollection is that it was a pretty healthy hike to the snack bar--no matter where your room was located from the south wing. (It can be a pretty hefty hike from certain room locations in the north wing, too).
I don't know if you would even consider walking over to the MK--but it is a bit closer from the North wing.
The south wing is closer to the pool.
We love the CR--it is the first resort in which we stayed at WDW, so we have some very fond memories. We have stayed in Bay Lake view rooms (which tend to be quiet, but far away from the tower in either wing) in which you can see the Electric Water Pagent from your room. When DS was 2 years old, he used to be so exhausted from the park experience, but he would not go to sleep until he watched the Pagent each night (at 10:05pm)!
