If you came on eVisa, you'll need a print out of that page.
I have found Pattaya to be unkind. You will likely need to make sure you have all your paperwork in order. Sometimes they require you file your paperwork a couple days before expiration of your current visa.
I use the visa service next to the immigration. They are pricier but at least the get the stuff done in one trip.
I applied and receive my eVisa from US, I was in the US but they didn't ask me where I was physically located and I doubt they check. You could use a VPN if you're overly concerned.
"Big" is a common nickname in Thai, as is "Joke", although I have only seen it used together for this guy. He must be somebody special because every time he farts, the news writes about it.
You don't have "7-8-9-11" support? Or you don't have the documentation for your "7-8-9-11". You must always get your documentation or else how will anybody know if you have "7-8-9-11"??
I have been in smaller hotels where they did not do the TM30. Most Airbnb's wont do your TM30. I have leased condos and the landlord gives me the paperwork with the expectation that I do the TM30.
If you dont have a valid TM30 done for you already. I would check into a cheap hotel and have them do it for you. I have heard Pattaya immigration, has in the past, checked with the hotel that the guest is staying there and has not already checked you.
