as I had mentioned in my original post, this was an unexpected last minute detour that just came up.
I had already booked my airfare from DMK well before leaving from Siem Reap in mid-January as I had intended on staying for the full 60 days in Bangkok.
However, as much as I love it here another two weeks just wasn't in the cards knowing that I'll be back in mid-November anyway.
No big deal back-tracking to Bangkok in early March to fly out, I was just curious about how immigration would look at this back-and-forth. I'll have my confirmations and reservations handy in case they ask.
