I'm sure a lot of people (though, I know not everyone, especially the ones who 'rent' DVC points) who stay at the deluxe properties would definitely want and are willing and able to pay for a chauffeur service, especially when run by the Disney brand. Though they can take a ferry to two of the parks, the idea of busing it to MK or DAK is, to some of them... I'm sure they'd just rather not. Some just can't. They can't.
