I went in Sep. 2000 and used Mears. At the time, they charged $20pp/round trip (I think, or something close to that). They went twice a week and you had to book a couple of days in advance. They picked me up at the Disney resort (BW). We had the entire day. Better than renting a car because you don't have to worry about getting and returning the car, parking, driving, directions, etc. What a deal!
