If never visited I would tour bus then u could drive thru after that
If you don't want to chance your car getting dirty or are not comfortable with getting stuck behind cows or other packs of animals I would suggest the tour bus for sure. However, if you don't mind d either of those the car was so much fun. We got to go at our own pace and we bought 2 bags of food so we could admire the animals and feed them for as long as we wanted. It was super chilly when we went so I was happy I had a window to roll up and get warm in between animals.
