On one trip with my girlfriends, a short 5-day western Caribbean, I made photocopies of my passport and driver's license. Well, we got to the port in Miami and where do you suppose my originals were? In the printer!!! This after checking with everyone else that they had their documents in order. I was lucky that we were only going for a short trip and I did have the copies with me. The personnel at the desk were most accommodating. I don't think that would happen today.
