Could anybody tell me how long it will take me to get to udon airport from Vientiane/ Thai friendship bridge, in a taxi, and cost please. Thanks in advance

Has anyone used the hotel transfer on Agoda? Thinking about using from Phuket airport to hotel.

We need to do our first Visa run. Came in on 30 day exemption and did one border bounce for another. Planning on being here through December at least. There are 6 of us. Flights adding up quickly. 1) Is our cheapest option to take a bus or maybe rent a car? 2) Vientiane the closest in that case? 3) it wouldn't count as 2nd land crossing as it would be a 60 day tourist Visa and not a end 30 day exemption, is that correct? 4) any better ideas or crucial bits I'm missing? 5)Thanks!!!

Edited to add: we are in Chiang Mai
