A detox vacation doesn't exactly sound relaxing, much less enjoyable. I've been on a few in the US, including one at Canyon Ranch, and they were miserable. For lack of a better way of saying it, all my previous experiences left me feeling like I was vacationing on a fat farm; worse yet, I gained weight after leaving Canyon Ranch because the food was so horrible I spent my days overeating granola mixes, bars, and energy snacks that were high in sugar and calories. Turns out, as with many other things, Europeans do detox better.
