Phuket is as robust as Bangkok for the test and go program. Plenty of hotels and the test and go system is well established there. Testing is done at the airport then you go to your hotel to await the results before being released.
you absolutely will not be allowed to board the plane without the Thailand Pass approval QR code. The airline is required to check very carefully because they are liable for returning you if they let you fly.
Just making sure you know Macau isn't on the list of quarantine exempt countries and territories so you won't qualify for Test and Go unless you spend 21 days in Singapore first or another country on the list.
The Agoda booking is not enough. The hotel needs to supply you documents to give for Thailand Pass approval and immigration so they need you to complete forms to send it to you.
why shouldn't it be pointed out? If the person doesn't know that visa on arrival is a different thing from visa exempt, they may look up rules for visa on arrival and get confused as it doesn't apply to them. For example, they may expect to have to pay a fee upon arrival or think they can only get stamped in for 15 days. This is no different than pointing out the distinction between O and OA visas which again are different rules and requirements, yet commonly confused as the same retirement visa by people posting.
You still need all the usual requirements of any foreign tourist visiting Thailand. At the moment, this consists of needing to apply for a Certificate of Entry (COE) from the COE website, which includes having to submit proof of insurance covering at least $100,000 USD for covid coverage, proof of your roundtrip plane ticket, and proof of your hotel booking for either an ASQ quarantine in Bangkok or Pattaya for 7 days if vaccinated or 10 days if not, or a Sandbox SHA+ hotel booking for 7 days with no quarantine, if staying in one of the Sandbox regions like Phuket, Samui, Krabi or Phang Na. These regulations may change once the government finalises the revised regulations that they plan to start in November but no one can give you final details yet since the government hasn't announced the final rules. For visa exempt- be sure to select visa type "medium term - visa exemption" as the visa type in the COE form. After getting COE, you just show up at the airport with your passport, COE, and hotel confirmation and insurance proof.
Be careful on the terms you are using. Thailand does not treat Visa on Arrival and Visa exempt as the same thing. You qualify from the Netherlands for Visa exempt, meaning no visa is required and you are just stamped in when you land. Visa On Arrival applies for those from about 20 countries like China and India where a visa is required but can be applied for and received at a kiosk at the airport upon arrival rather than through a consulate before travel. It is important you don't use the wrong terms since if you look up regulations and rules for visa on arrival rather than visa exempt, you will see incorrect info that doesn't apply to your situation.
can't be done. The airport officials have an exact list of incoming passengers and what ASQ Hotel they are at and escort you through baggage claim and directly to the specific driver from your hotel that registered with the airport that they are waiting for you.
