We had a lovely time with Mr Thailand on a tour of Koh Samui. He was prompt to pick us up from the hotel, with a lovely, spacious car. We enjoyed the tour, apart from the Namuang Waterfall. My mother, who was on crutches after a knee operation, was on the tour. He didn't tell us that there would be a steep 40 min climb to see the waterfall. As a tour guide, I would expect this information to be given to us before we attempted the fall. Everything else was fantastic on the tour! He showed us everything we wanted to see, and we enjoyed our day! He provided us with lots of cold water during the journey which was much needed.
