Just another opinion, but I always found it more convienent to drive; it allowed us to stay as late as possible at any park, without having the cattle rush onto the busses or monorail. After spending a whole day packed in with everone else in the park, any time I could break free form the crowd and not have to worry about standing, getting in line again, etc. was a bonus. Also, we always paked a styrofoam cooler in the car, adn you could have cold drinks and snacks for the ride home.
