Thailand is like a box of smarties, it's not the Thailand like what you see in the travel magazine now BKK/ Pattaya/Phuket are full of tourists and expats running the show.
Already back in 2010 when I went to the UK I stayed outside London and to be honest I didn't have any British person as a friend or working in my company.....
Sorry to ask I don't know too much about this.... If you are on a non O marriage visa which is for one year with a 90 day reporting why are you doing border runs ?
