Hi Guys , just to help ref to my question " can I do 90 day report in Patong as on hols here , while live in HUA HIN " , yes you can , all the immigration lady said I should have put form in where I was staying in the first 24hrs but no prob , as I said thought the hotel did it after taking copy of passport . ,if going away while your 90 day report is due you can report in Patong if visiting . Hope this helps , I'm no Todd master.
