So, the new that has been added is to tell the first day where you will stay on day 6-7 for your 2nd PCR test. How would I know where I stay by then! I need to check how to get to Krabi and that might be by train. Or if stay in Bangkok I will stay in Banglamphoo but not sure where before I am actually there. So is it really necessery to provide the info on your first day on the "Port Health Letter" as it is called? Flying in to Bangkok Test & Go.
