Another way to make it even more fun, is to park at downtown disney (or one of the resorts for that matter), and then take disney transportation from resort to resort, (bus goes to all resorts) - or, you can take a boat from downtown disney to Saratoga Springs, Old Key West, Port Orleans. You can take a bus from one of those to a monorail resort, and hop to other resorts on the monorail. You can do the Epcot Resorts by boat or walking from one to another. And, when you're through, all the resorts go to Downtown Disney so you can fetch your car!
Leave the driving to disney! Have a wonderful time!
