Because I was worried about missing the bus, I chose to charter a car. Although the price wasn't very cheap, it saved me time and the risk of getting lost, so I still felt it was worth it!
The driver was very attentive, providing rain gear and even helping with photos. He was very helpful, and the attractions we visited were all beautiful. Although it was a bit of a rushed tour, it was still a comfortable day trip.
