Hello! We are planning our first trip to WDW in April, staying at Wilderness Lodge. We will not have a car. My question is that my Mom who lives in FL will be visiting us for a couple of the days, staying off site. She will meet us at our hotel and take the disney buses to the park with us. Will she be charged for parking at the Wilderness Lodge? AND will she be allowed to ride the buses with us, (never been, not sure how the buses work?)??? I assume the buses aren't only allowed for guests staying onsite, because anybody can take the buses to other parks, resorts, etc correct?
