keep in mind that Bangkok is NOT issuing the 60 day covid extension on the spot, you get an under consideration stamp and then you go back to that same immigration office on that date and get the extension inked in.
Might be better for you two to just apply for the covid extension where you're staying (seeing as you have a TM30 filed in Pattaya) rather than needing to make another trip to bangkok to "close the loop" on an under consideration stamp
