I just read something sent by a friend that is in the Thai news. They are now working on a plan, at least for some tourists, to have bubble areas within Thailand. They are proposing several select areas where tourists can stay quarantined for 14 days while visiting the sites within the areas but not leaving for other areas. They were talking about a requirement of a specific type of covid testing just shortly before arrival which must be negative and then an additional test at the end of the 14 days to be able to go to other areas in Thailand. This apparently has not been passed yet but is moving through the chain of consideration.
