I live in California and travel to Thailand frequently for holidays. I arrive at BKK this coming Wednesday, 27 April, so will still have to go through the "Test and Go" routine. Bad timing on my part! For future trips, I'm very happy that the process will be much simpler. Although Covid insurance will still be needed, getting it for my upcoming trip was really simple. I bought 700,000 Baht of coverage for 60 days over the internet from a Thai insurance company using my credit card and received the insurance policy in less than 24 hours. The total cost was only was 1,050 Baht. Now that the coverage limit is being halved from May 1st, the cost will be even more cheap. I don't think the requirement for Covid insurance will deter anyone wanting to visit Thailand in the coming months.
