Long range planning. Very experienced world traveler but will be first time in Southeast Asia. I will have a weeklong conference in Pattaya, Thailand next May. How realistic is it to travel by car from Pattaya to Ho Chi Minh City via Angkor Wat and Phnom Penh? Ideally we would do a one-way rental if that were possible.

Thanks for any insights.
