OK, we got our 30 day extension to our 45 day visa exempt entry today at MTT. Got there around 930, out in less than an hour. They didn't want the tm30. Jomtien always wanted it and the wait was always long.
Grab taxi from Nana plaza 250 baht plus 95 for highway tolls. Taxi took us all the way behind to the tented entrance. It is counter k on the 3rd floor. No one in line.
Grab taxi back to Nana square 225 baht no freeway.
Thanks all for the help and advise, it was easier than I thought it could be.
I don't know if we could have gotten the 60 day covid extension, but I think the timing works out to get it next month just before it expires, which it likely won't.
