I was asked to throw in my two cents.
I've said this on another thread as well. Mexico..the repo cruise appears to be hitting a port where it has been said
DCL is saying passports will be needed. The central american countries are starting to crackdown on there entry / exit requirements. Over the years you could come and go and get away without a passport for travel. Your odds are not as favorable now. The FCG states that you need to keep your passport with you at all times while in Mexico or you need to get a travel card. I'm not sure how DCL will handle this situation with travel cards and it might be best to talk to them prior to going. Also please check the state dept travel advisories concerning Mexico and some crime issues that have become problematic to safety of foreign visitors.QUOTE]
This is what is on the State Dept website:
Getting Into Mexico
The Government of Mexico requires that all U.S. citizens present proof of citizenship and photo identification for entry into Mexico. While U.S. citizenship documents such as a certified copy of a U.S. birth certificate, a Naturalization Certificate, a Consular Report of Birth Abroad, or a Certificate of Citizenship are acceptable, the U.S. Embassy
recommends traveling with a valid U.S. passport to avoid delays or misunderstandings. U.S. citizens have encountered difficulty boarding onward flights in Mexico without a passport.
Tourist Cards
U.S. citizens do not require a visa or a tourist card
for tourist stays of 72 hours or less within the border zone, defined as an area between 20 to 30 kilometers of the border with the U.S., depending on the location. U.S. citizens traveling as tourists beyond the border zone or entering Mexico by air must pay a fee to obtain a tourist card, also known as an FM-T, available from Mexican consulates, Mexican border crossing points, Mexican tourism offices, airports within the border zone and most airlines serving Mexico. The fee for the tourist card is generally included in the price of a plane ticket for travelers arriving by air.
What it is not clear about is cruise ships and if ports are considered "border zones".
