Oh wow, thank you guys for those many replies!
We were really worrying about the entire process and preparing to pay our hosts, even tho it feels like they are taking advantage of us..
Our permit expires on February 1st and we are in Pattaya so we will go to the immigration office in Jomtien.
We are trying to call up a hotel nearby to ask them if they file the TM30 and provide us with a copy of it, to make sure this goes smoothly.
Someone warned us that we might have to pay a late submission penalty, do you think this is likely?
