Just be aware that driving to resorts might take longer than taking Disney transportation. When you drive to the MK, you will have to not only come all the way in from the parking lot, but also traverse through the TTC and on to MK. When you take Disney transportation (which is free), you will be dropped off right at the entrance. For Epcot, you just walk over, and for MGM you can either walk or take the boat. AK will require the bus again. Not sure how buses are from BCV, but they are great from OKW. The only time we really use a car at WDW is when we want to go to one of the other resorts for dinner, etc. Disney transportation takes a bit too long for those kinds of trips, but parks are great to get to.
