You might want to request the 2100 loop. It backs up to an RV loop that has a comfort station, and it's a very short walk to the Meadow pool complex with the main feature pool and snack bar. The bus stop for that loop is across the street by the 2200 loop. 2100 is very centrally located in the campground, so if the weather isn't bad, you could actually walk most places - figure about 20 minutes to Settlement or Outpost from there.
I disagree that you HAVE to have a golf cart. Is it a convenience? Yes. A necessity? No. The bus transportation will get you where you need to go. I have never had a "half mile walk" to my cabin from a bus stop. If you do decide to rent one though, Kenny is the guy to work with.
