Ratchaporn Poolsawadee, president of the Tourism Association of Koh Samui, said some minor rules still need to be finalised, such as the cost of a 7-day alternative state quarantine (ALQ) package that should cost 35,000 baht, including swab tests and medical fees. While many provinces, like Phuket, impose more stringent measures for local travellers, he said Koh Samui will not ask vaccinated travellers to show negative Covid-19 results.
