Seudamgo ferry is the last one from Ko Kood to the mainland and you make it on time to Trat airport for the Bangkok Airways flight in the afternoon (low season August 2023). To book tickets online is difficult since the office does not offer Paypal payment. 12go Asia is helpful here. The ferry ship is smaller than other ferries. It is modern and safe, but keep in mind that it shakes a bit more on the water. In the low season it can be difficult to find a transfer service to Trat airport (transfers seem to be overpriced, only Boonsiri ferry offers a reasonable price).
When we were supposed to go by transfer to the pier from the hotel, we lesrned that there was no boat at the booked time.
We had to stay one more day at Koh Kood and lost our appointments in Bangkok and Ratchaburi for that day.
The shipping company gave us one night hotel in one of their resorts, but the problem we had could not be solved.
Just in time and good organisation. A taxi from the pier to Trat City for 100TB per Person.

Everything worked out. But unfortunately no one told us how the transfer after the ferry would work. As we didn’t know we should rush, the initial shuttle to the airport was already gone. So we had to wait 45 minutes for another one. Everything worked out, so all good! But it would be great to inform the customers a bit better about the different steps.

As far as the drivers experience is concerned, everything was good, the driver was very professional and nice, nothing to complain about. But the operator on the phone( Shine exclusive) was a tragedy, very rude behavior, when I was trying to find the taxi he hung up on me in the middle of conversation with the words: wait and stop asking the questions. Never seen that before..he made a mistake and was rude instead apologizing. I have whatsapp conversation if needed. Never again

8am pickup was 25 minutes late. 9am ferry left exactly on time. Still, we only arrived at Trat airport at 12pm, although the booking info said 10.45am. We were glad that we planned sufficient buffer.
