I'm going to be staying in Railay East and have a 930am flight from Krabi Airport. I read that you have to take a long-tail boat back to Krabi town (45minutes) and then catch a cab (15minutes) to the airport. That means I would need to leave Railay by long boat about 630am to get to the airport to make my flight. Do longtail boats leave that early from Railay? If not, I have to forfeit my reservation and ride into Krabi-town the night before to make my flight that morning. Any suggestions?
