I'm in the process of arranging to travel, in late September, to Phuket, using the Royal Thai Vacation services. They've offered to provide my SHA PLUS hotel accommodation, SHA PLUS airport transfer to hotel, COVID-19 insurance cover, arrange my three prepaid RT-PCR tests and actually handle the entire COE application. So far, all that I have had to do is provide them with my passport, flight details and vaccination card. To be honest, it is quite expensive compared to sorting out the process, on my own; however, after getting a very confusing run around, at the Thai LA Consulate, on my initial COE application, coupled with the hassles searching for insurance, at 75 years old, I figured that the extra cost would be worthwhile. Of course, the proof is in the pudding.
