Thank you Mr Samui!
I was extremely grateful to be able to book a driver with very little time in advance to explore the island as a solo traveler with a restricted schedule. It was also easy to book (through WhatsApp) and pick up was for the same morning as my initial inquiry.
My driver, Chicken, was extremely knowledgeable - sharing facts about the island and places of interest as we went along. I honestly was not expecting this level of service so it was a nice surprise. He really goes above and beyond for his work.
I would recommend Me Samui of you are happy to pay a bit more (although it would not be so bad if split between multiple people) for a comfortable, efficient, safe and high quality service
