I'm a vaccinated foreigner that's been on Koh Samui for almost 14 days. I had negative test results at both the airport when I arrived and on day five when I was staying at the resort during the first week. After day 14, does anyone know if am I able to go to Koh Pangan without being tested again or showing proof of the first two negative test results in Samui? And I never received proof of the negative test results but I am currently asking the resort for copies of them just in case. TIA for any info.
TLDR : Answer Summary
A vaccinated foreigner in Koh Samui, after having two negative tests and completing 14 days at an SHA Plus resort, can travel to Koh Pangan. It's important to obtain release papers from the hotel, as these may be required for movement within the country.
