Across the river from the main town of Vang Vieng are a couple of places which provide cheap bungalow accommodation with hammocks. Even if you're in town for tubing, the all night party noises are not what you want for the duration of your stay. On this side you can relax in your hammock by the river and choose to join in the fun on the other side if and when you're ready instead of having to put up with it.
