What is the process for obtaining a 60-day Covid extension for a visa exemption in Thailand?

UPDATE:

Thank you all so much for your responses and help. Today we went to the Temporary Visa Extension Office in Muang Thong Thani, Nonthaburi (including people from the Bangkok area) around 9:00 am and were quite HAPPILY shocked to find we barely had to wait. We had expected hours of waiting, but perhaps because we were doing tourist Visa exempt extension at Counter K, it was much less busy. I think we were pretty lucky though, as there were at least a hundred chairs in the main room which I imagine generally get put to use. By the time we were done, there were about 10-15 other people waiting.

We were told (as expected for this location) that we had to get the 30 day extension first and could get the 60 day extension later. The people were friendly to us, though there was a lady who was rude to 2 different groups of people by the time we left (everyone else at the other stations was polite, so hopefully you just won't get her).

In case anyone else is going for this extension, the documents we had to take were:

-Passport

-Signed Copy of passport photo ID (we originally printed just the page with our photo, but apparently for US passport, they also wanted the page directly above it with our signature. This wasn't an issue as our friend who came to help (in case translation was needed), just went out of the room and made a couple of copies and brought them to us.

-Signed Copy of passport stamp page from our entry into Thailand

-Signed Copy of TM6 departure card

-1,900 Baht per person

*For signed copies, we were told to write our signature below the image on each page

My husband despiiiiiiiises admin/bureaucratic processes and was dreading today because of issues we've had even trying to find this was the office we should go to etc., but he keeps saying to me (after we finished this) "I'm so happy it's done!" He's just shocked it went so smoothly. The 30 is done for now, so here's hoping our 60 application will be as easy.

Best to you all and thanks again!

*END OF UPDATE***

Hello! My husband and I arrived from the USA on May 19th using the “Visa exemption scheme” and are staying in Bangkok.

We want to do the 60 day Covid extension. Does anyone know which offices in/around or even a little further outside of Bangkok are willing to do this for us? We’re planning to go to the temporarily operating Visa extension office (set up because of Covid 19) on Monday, but I’m afraid we’ll wait hours just to be told they’ll only give us the 30 day extension.

Has anyone had experience with this? Thanks for any help! 🙏
