I was unable to get an extension of stay at Phetchaburi immigration because my hotel said they only issue [whatever that address proof is called!] to people staying one week or longer. Is this normal in Thailand? Is there an immigration office where it's easier? I'm Canadian on a 30 day visa exemption, expiring Dec 23. PS I've used up my two visa exempt land entries for 2018. I'm hesitant to fly out and back in after hearing about people getting refused.
