No issues whatsoever. My wife is a Canadian citizen and US permanent resident (green card holder). Port security in Mexico has no idea what anyone's citizenship is. They are not checking ID when getting off the ship and you can just show them driver's license with your S&S card when getting back on the ship.

I am so so so happy to hear that. I booked a cruise to take my parents to Mexico, Jamaica and Cayman Island in June 2014. Mexico consulate website indicates that green card holder need a national passport to enter Mexico but it doesn't sound like they care for it. When getting on the ship here from the USA port, did custom and immigration officer asked for her passport? When I read the custom and immigration website, it said that from the US perspective, US only needs to see the green card to enter and exit the country but would like to hear from you who went on a cruise recently. My parents don't have their national passports . Did the US immigration asked for her passport?
People who travel outside of the US should have passports.
If there is an emergency that disrupts your travel plans, a passport is a must.

My husband is a Costa Rican citizen, US Permanent Resident (green card holder). He ALWAYS has to fill out his Costa Rican passport information as well as his green card info when we book the cruise, and he has to present both documents when we check in. Always. Every cruise.
