Our driver, Mr. John, is reliable and steady. He is polite and punctual for pickups, and always ensures we have water to drink. He is flexible with changes (within the itinerary) and offered recommendations. He even helped me glue my sandals when they broke. We communicated through Google Translate without any issues. I highly recommend using TTD Global. The SUV is spacious enough for 4 adults and 4 pieces of luggage. It's clean with no strange smells, and the driver doesn't smoke, which is a bonus! The only pity was that we didn't see any wild elephants! But we did manage to see hornbills, deer, monkeys, and millions of bats! Mr. John let us use his binoculars to see the hornbills in the trees. We are very thankful. He provided information about the places we visited. Khao Yai is a very beautiful place for everyone to visit. We came in December, and the weather was great!
