We have never rented a golf cart either. I can't justify paying as much per day for a golf cart as I do for my site. We alway get a site on the marina end of the park and have easily been able to walk where we wanted to go. The buses seem to be a bit of a hastle especially with a stroller, but we avoid most internal bussing by staying on the marina end. If I need to go back to the Main desk I can take a bus, otherwise no need. Bicycles also work well if you have older kids.
