we prefer the ultimate flexibility that having your own car offers...we've done the
DDP and the DxDP and loved being able to schedule resort restaurants wherever/whenever we wanted. "Traffic" is never so heavy that it takes longer than Disney transportation...we usually figure 15-30 minutes with the car, but 60+ for using Disney transport. And some places are really time-consuming to get to (like Turf Club at Saratoga Springs...great restaurant, but not easy to get to unless you want a fairly long walk from Downtown Disney bus stops.) With a car, it's easy to get to. Same with Olivia's (Old Key West) and Maya Grill (Coronado Springs)...great places to eat and easy to get to with a car. Once you catch onto how the traffic flows around Disney it's very quick to go from here to there within Disney.
