I have heard mixed things here, so I am wondering: fiance' and I are traveling to Puerto Vallarta and Yelapa for our hm, and I know that we should only drink bottled water, but what about frozen drinks? They are blended with ice, but do you ask if the ice was bagged to make sure. Wouldn't that be rude? Is the bagged ice going to be safe? I know it's going to be hot there, so I'm really hoping we can have iced water/ drinks!
