I want to repeat that the DTD hotels have good transportation. Their buses run all day at scheduled times. I've stayed at the old Marriott (now Holiday Inn) and had great trips. With multiday passes you can use Disney transportation, so sometimes we'd take buses to DTD and walk to the hotel.
We do like to rent a car--like to go off-site for food, groceries, etc. But Pop Century seems to have good bus transportation. We only used it for MK and an enight in August, but it was great.
