I'm in the same boat, have paid for a PCR, I guess will be hard to get a refund for the much cheaper ATK but as many have said here, wait, it's a moving target.
apart from issues using Chrome (I had about 4 attempts & couldn't get past the first page, this was before it was acknowledged that you need an extension to Chrome), I used Firefox & no issues. My insurance was in Singapore Dollars for 250k which they obviously could not convert to USD?
I'll use the Hotel booking as it was less than 50 USD for a beach front room. My Condo hasn't been lived in for 22 months, so I don't know what I'll find.
just the voucher. This was 2 weeks back. I've since contacted the hotel to book a transfer & then register to get a PCR test on PSAS. With the test voucher & Hotel transfer, the hotel gave me a letter with a serial number for immigration.
For my upcoming trip to Phuket I booked originally SHA+, I received my Thailand Pass on this booking. I didn't expect the transfer nor PCR for the one night hotel price. I contacted the hotel on Monday, they provided a link to book & pay for the Test. I then sent a copy of this to the Hotel with a transfer booking. They sent back a official (from the Hotel) letter with all this listed & tied to the Hotel booking for me to show to Immigration.
It's both a little complicated & expensive now to come to Thailand. Certainly my long weekends in Phuket are a thing of the past for the time being. I can break down the real costs if anyone is interested.
