You step off the air-conditioned minivan into the humid rush of Pattaya, the sea already calling — a ribbon of foam and sunlight where the speedboat will cut a path to Koh Larn. The engine rumbles, the pier slips away, and the Gulf of Thailand opens like a bright, moving map: water daring you to wade, reefs nudging at your curiosity.
