We are driving to WDW from OKC in May. My minivan has 100,000 miles on it and we will do a tune up before we go. Would you pay to rent a car or just pray your own van makes it there and back without any problems? My van doesn't have any real problems and I would like to save the money and not worry about my DS 8 and DS 6 spilling something in a rental. But I would also hate to be out in the middle of nowhere and have a breakdown. WWYD?
