Would it be to much to leave Vang Vieng on the first bus and be able to catch a flight from Udon Thani at 4pm that day?
It seems that V.V is 3 hours form Veintiane and another 3 to Udon Thani. Hopefully arriving at Udon Thani at 2-3pm?
Does this sound about right? We would hate to miss our flight.....
