yeah I know what your saying, you’re one of luck ones that are going for the long haul so even though the quarantine will be difficult it won’t really affect the time your going for. It does say you should get your Thailand pass for the Phuket sandbox within 7 days so you’ll have time to apply for a new pass. Id just make the decision now to go the sandbox route and contact your airline to change your outbound flight and apply for a new Thailand pass. But that’s me mate good luck with what ever you chose
