If you’re absolutely vaccinated and you do not need to quarantine, you have to arrive from Germany to Phuket with transit in Singapore. Please verify with the Provincial Government of Chiang Mai about their current entry restrictions. You can journey from Phuket Airport and go to your SHA+ Hotel in Phang Nga. When you apply for the COE, you still have to decide on Phuket Sandbox and you still should do your 2 COVID checks, perhaps in Phuket also, until it’s arranged by your SHA+ Hotel in Phang Nga.
International tourism entails tourists who are touring to international nations. An example of worldwide tourism includes a Chinese tourist visiting Rio de Janeiro. Since these vacationers cross worldwide borders, they have to carry a passport and visa and exchange their money into the local forex.
