Well, until our holiday just gone, we always used Disney transportation (and regular buses when staying offsite), but just before we went on our last trip, our mum got ill and is now in a wheelchair. While the Disney transportation was wonderful in being accessible for the wheelchair, by the end of the holiday it got to be too much hassle, so when we go next time, we are renting a car, and will see which works out better for us. If we had no wheelchair, then it would be Disney Transportation all the way, but since we do now, it might be time to switch to a car, for the first time in 10yrs of vacationing!
