As a means of transport, minibuses can be okay I suppose. It depends on how many people are put in, where you sit and the route. The ride up from Vang Viene was a wonderful trip, well for me anyway. I got to sit up front in the van and got to watch the gorgeous scenery roll, jut, loom and flow past. The country looks like a tropical Scotland. Rugged mountains litter the landscape in a similar haphazard way, but these guys are covered in lush green forests.
