, you are wrong.
From 1st April everybody will be in 10 days quarantine, according to the Thai government.
But the hotel will force you to stay 11 nights.
If you are fully vaccinated, then it is 8 nights.
Only exception are those travelling from African countries, they must still be 15 nights in quarantine.
And it is one more thing.
The Thai government will update their list of safe countries two times per month.
