Experience on a boat or not.
If I ever should go to Samui, it will in the most convenient and cheap way, which means taking a flight to NST and a transfer to Samui. Alternatively I could also imagine a train journey.
For sure I won't use Bangkok Airways.
If the seahorse ferry can beat the price, I'm all in
But it starts already with the problem, how to get to Sattahip.
From my current home, I take a taxi to Swampy or train to DMK.
Can't leave the family car for a few days somewhere
