Hi all - first post I have been lurking for a week or so since it was decided we are going on a W.Med cruise next february (2014).. Anyways, I have read post upon post about the passport issue. I totally understand the benefit of having one in case of emergency and not being able to re enter the US via air without one etc etc. I get it, but my family does not believe me that it is NOT required for the ports of call and excursions for the cruise - does someone have that from a verified source that they can link me to? For example - if we dock at cozumel and go on an excursion or get off the boat there - my brother and husband are both convinced we need our passports. I know from reading various posts and what not that is not true but they don't believe me, LOL!
