As others have said, the bus ride itself may be short, but if you get there right after a bus left, your total wait time could end up being longer. I guess this just doesn't bother me, even the times we've waited, it is just the way it is & my getting upset won't change it. And in my mind, waiting for the bus is less painful than getting lost trying to drive to the park myself (and since I can get lost driving in a straight line I'm sure getting around WDW is well beyond my navigational skills). It also depends on other stops & guests. I've seen stops where it took 10 minutes for people to realize this is their stop, collect their stuff & all the people in their group, ask the driver 57 questions & finally pile off the bus. Obviously that slows the trip down for everyone else still on the bus.
