I agree with SXMScubaman, when there's water shortage issues, people tend to cut corners and not use proper hygiene practices. I got Hepatitus A (no running water) from sewage contamination at a beach bar in Nevis (ST. Kitts). When we're spending a lot of money on a vacation, the last thing we want to worry about is getting fresh water. For that reason alone, we would never stay on the French side.
