Hi guys, for doing border run on my own ,what is the exact bus (or buses) to take from surathani Pier to Malaysia border and how to see the schedule and book?

About getting a visa in Vientiane, at Udon Thani, are the buses/vans driving till midnight? I would arrive maybe at 22:30 at the airport. What time they start and stop driving? (i could also go the next morning, but maybe that would mean I will be too late for that day)

Is there a schedule available when the buses/vans drive to Vientiane? (I would have to make a Laos visa at the border)

And do all buses allow you to do to make the visa at the border?

The best days to go are still tuesday/wednesday and just 1000 baht + 2 photos + copies?

does anyone what time the last bus is from mukdahan to savannaket is on weekdays
