We enjoyed the tour and learned amazing things about this UNESCO World Heritage Site. My only regret is that because it was just a half-day tour, we did not have time to see the museum and learn interesting things there. The tour guide was kind. We were 10 minutes late during pick-up because we changed hotel the night before but he patiently waited and we were able to make it. Although, I rated this tour perfectly, I would just like to suggest if it is possible that the included lunch should not serve egg. Egg is my most favorite food. However, it is not really a fit for lunch. I notice that all of us in the tour group, composed mostly of Westerners, did not eat this egg viand, so it was really a waste.
