Thanks everyone for sharing your views. I'm normally all for the disney buses as they take all the worry out of going to and from, but I am thinking of staying at the Epcot resort area and I remember the buses being horrendous there. I've never had a worse bus experience (regarding time) than I did there. Sure I can walk to and from Epcot and DHS, but it seems like you 'pay' for that by having horrible times on the buses to MK and DTD.
I'm not sure where the parking lot is at MK. I don't remember seeing one.
