Same a everybody, you need to get few documents ready to submit to the Thai embassy and 14 day quarantine, maybe New year 2022 as 2021 will be short in time to get yourself ready :)
Maybe depend on the hotel. I have a friend which is in bkk now , just arrived from Olso and he can not move out from his room the first 7 days. anyway it is only 14 days and if you can not miss the gym or the pool maybe you wait till Thailand reopen as normal ;)
