This appeared on a Not Everything Else site and typically there was a single response before commenting was closed. The comment was that it was unconfirmed, but, as nobody seems to have tried actually contacting Troy Bakes, I did. He is stuck in Cambodia but I suspect his problems lie elsewhere than reentry being blocked due to time spent in Cambodia.

I have just got back from Chong Chom and I can assure everyone that there is no problem with the standard visa run for the purposres of a valid visa - mine a multiple O based on marriage. In and out in less than 20 minutes. Temperature checks on both sides and a squirt of free gel on the way back into Thailand.

New restrictions coming in from tomorrow for entry into Cambodia mind. Not confirmed as yet .... probably ;-)

Just got back from Savannakhet. Multiple O for Marriage was easy. The only doc the IO studied was the original red-bordered marriage certificate. A grand total of 7 pieces of paper submitted. Only down-side is that Savannakhet may be the most boring town in Asia.
