For some reason, a few restaurants there always have DVDs of Friends playing. There is also a restaurant that started showing How I Met Your Mother for the younger generation, but we are loyal to Friends.
Tubing is a huge attraction in Vang Vieng. People rent an inner tube and float lazily along the river, bar hopping all along the way. We opted to go kayaking and were assigned a guide who only held us back. He lost his flip flops, twice, and then his paddle got stuck. We passed so many bars along the way claiming to be the last bar until town, very amusing.
