I consider myself a traveler. I’ve been around a few continents.I would NEVER go on a cruise, packed with people I have nothing in common and probably despise, forced on a ship that I have no control over (I did sail a few nations with friends and I loved it), a ship that looks like a giant mall/casino… sounds like worse than hell to me. I can’t comprehend why people pay for that.
Tap water in Italy is also more controlled than bottled water. Not sure about the rest of the world, but I wouldn’t trust commercial water to be kept at higher standards than tap water.
It’s not an adventure if you’re under someone else control.
