Our tour guide, Sunny, was humorous, witty, and professional. We had a wonderful three-day trip. Thank you, Sunny! 👍 The itinerary was also very well arranged. We ate, drank, and slept well, and were taken very well in. The travel time was naturally a bit long due to the distance, but it was acceptable for the beautiful scenery.
