We decided to take a long weekend trip from Pattaya to Hua Hin, a few days after the New Year. The Pattaya-Hua Hin ferry was about to start service. They were even offering free passage for the first week or so. We (wisely) decided to give it a pass until the reviews came in. So, we drove. From what I have heard, the ferry has had to cancel trips when the water is too choppy. Just bear in mind that if you’re planning a trip, you may not be able to count on getting to your destination when you planned. We ended up driving using our trusty GPS. The trip took about five hours including rest stops and coffee.
