We took a mini bus from Luang Prabang to Vang vieng, ahhhhh is all I can say. It was the most terrifying journey, we spent 7 hours on the edge of a mountain side. Felt like I was on worlds worst road truckers program. I just couldn't look out the window over the edge. Plus vehicles come from both directions when there's not a lot of room. Strangely the driver decided to do his shopping on the way, buying from villages from the side of the road and even bought a live rat which was hung on a rope to kill and eat later on, another world!!! Eventually we arrived safe at our destination but had only allocated one day to do the tubing. Unlucky for us it was torrential rain so we ended up watching friends in the local cafe all day and moved on.
