I think everyone would agree that it's much easier with a car. There are still a lot of people who don't bring one, and yes the transportation does get you where you need to be pretty much. Dynamic was kind of slow, someone said the new one is a little better, but I wouldn't know since I never experienced it. But yes, when I was there the buses took you everywhere on disney property, walmart, the post office, the crossroads (it had restaurants and stuff), and a Publix (which you can actually walk to from Chatham. Once you get used to it the buses really aren't that bad, plus you can meet people on the buses. If I go again though I think I'd defintiely want to bring my car, but I did okay without one my first time.
