Everything went smoothly, from pickup at the airport cafe, to the drive (with multiple rest stops for bathrooms and food) and the ferry ride. Totally worth it. It was better than expected!
took a transfer from phuket to ko samui. the trip was good, but it is worth mentioning that the route is different than the operator indicates.
first you go to suratthani by minivan, then wait about 30-40 minutes and transfer to a large bus and go to donsak pier, and only then you are taken to the pier
He came to pick us up on time, unfortunately we were not present at that time so he came back later. The driver was professional, took required breaks, carried luggage properly. The AC Temperature seemed perfect and our journey towards ferry was also hassle free.
