Good riddance. I passed through Vang Vieng earlier this year and lasted about 18 hours there. A beautiful area of Laos turned into the quintessential backpacker shithole, replete with drunken/high, shirtless Brit and Auzzie dudes and overweight girls in bikinis. The worst bunch of foreigners I've ever met in any place ever (and that includes the sexpats of Thailand!) The trip down the river via tube, kayak or otherwise is visually stunning; the riverside "bars" with their Mad Max-esque structures, incredibly dangerous slides, rope swings etc. and aforementioned clientele won't be missed.
I can't have sex with your personality, and I can't put my penis in your college degree, and I can't shove my fist in your childhood dreams, so why are you sharing all this information with me?
