I received an email from TTD a day before with driver information, and TTD responded quickly via WhatsApp messaging. The driver, T4, arrived 10 minutes before schedule. The car was comfortable. T4 took us to the sites listed on the itinerary, allowed sufficient time for photos, and helped us take group photos. The waterfalls were impressive, and the viewpoint was breathtaking. We saw many monkeys. It was a lovely trip.
