On the subject of staying in prison/hotel lockdown in case you did took the effort to visit LOS: recent messages from other fora, mainly main Thai str8 couples, it is not too shiny.
It seems since the discovery of the british strain of covid Brits are completely banned from entering (or maybe this has since been changed) and whereas before some of the quarantine hotels were reported to be a bit more permissive after the 5day first testing, this has also been changed back to very strict isolation. So far for now.
