We had a similar experience. Our driver was also new. He missed his turn or road and we ended up going off Disney property. He turned around and found his missed route. We've had some slow drivers and some fast ones, but have never felt unsafe. We really enjoy the ones who give us all kinds of trivia and are friendly. All in all, they do a fantastic job especially with all of us tired and cranky people at the end of the day. It is a wonderful vacation when DH can park the car and leave the transportation woes to someone else.
