You know there's no point in trying to explain things to some people. Yes, it shouldn't happen, yes no one should be wasting their vacation time straightening out things that shouldn't be messed up. BUT, I always take printed and electronic versions of excursions, dinner reservations, OBC, insurance particulars, Terms & Conditions contract flight & hotel reservations etc. I don't depend on company's systems to always get it right. It's actually getting more and more prevalent that mistakes are made.
