As a newbie getting ready for her first trip to Jamaica- first trip out of the US really, aside from Cabo and a couple of cruises... I am NOT well versed on out of country travel. I truly appreciate all insight and tips here on this forum. I have what is probably a stupid question, but... here goes anyway. I've read that you must carry your US passport with you at all times while in Jamaica. Well if that's the case, I don't see people carrying their passports while swimming. I've heard some people say carry a photocopy, others say photocopies will do you no good, but keep a photocopy somewhere safe in case your passport gets stolen. What's the real deal here... passports necessary while you're out and about, whether swimming/walking the beach/going to dinner, etc?
