Both Thai and Cambo Immigration are open 7-days/week.
I recall that they close at 6 or 7pm(?)...but from Pattaya you'll easily get there within about 5-hours.
More, if stopped for speeding on a Ducati :shock:
is Aranyaprathet open for cars as well? Docs in hand are complete (blue book, ITP, passport, visa, int driving license); Thai international plates (all English) and vehicle registered in my name. Presently dealing with a travel agent in Phnom Penh on legal paperwork - :crazy: - which seems to be an endless ordeal. Any hint highly appreciated.
