maybe go apply Monday for a 60 day covid extension, if they won't do that get the 60 day visit thai family extension, then see what's what closer to when you're leaving and as you said take the 7 day get outta dodge extension denied stamp (that you have to get just before your current stamp runs out because it starts the day you apply) and then pay the overstay if you can't get out by then
