We were in Vang Vieng in April 2011. My Husband spent a day doing the tubing experience with a friend. He came back pretty freaked out. The Drinking was excessive. People were drunk and jumping off of high pedestals over the river and getting hurt. Our Guide was very wary about anybody in our group going out on this excursion. Later that night we heard from our tour guide that 2 tourists had died during the partying from drinking too much then swimming. 2 adult men had died in separate accidents that day. This place can be pretty awesome but you have to realize that the the locals will NOT cut you off at the bar they will give you anything you pay for and even some for free. Even if it unsafe. They are poor people and even a dollar can make their lives much better. Please drink responsibly.
