Do you need a passport for all cruises?

On most cruises yes. But not on "Closed Loop cruises" see http://getyouhome.gov for all the passport rules!

cruises to the Caribbean and Mexico can be taken with a birth certificate and a picture ID

You will need a passport when you are taking the cruise outside of the US. The reason why is so you are in different ports that you are outside of the US.

All cruise lines strongly recommend you get a passport, but it's not required for "closed loop" cruises in the Western Hemisphere. http://www.cruisesavvy.com/savvyguide/know_before_you_go/do_i_need_a_passport

yes i been one 18 cruises and you do For US and Canadian citizens, you just need a valid passport, good for three months after the contract. All other nationalities need to secure a C1-D Us seaman's visa from US consulates in their respective countries. This just takes two days to get. Actually, on some cruises you only need a sea-pass. Which is the sea version of a passport. Passports from certain countries can not be used in certain cruise lines. A sea-pass should work for all of them.

Only if you start or end in a foreign port. Cruises are considered closed circuit journeys and as long as you begin and end in the United States you do not need a passport.

Holland America provides cruises to a variety of locations, most of which do require passengers to have a passport. The cruise line recommends that all guests have a valid passport, with an expiration date more than six months beyond the date of the cruise.

If you're a US citizen and planning to cruise to Alaska on a cruise that stops in Canada before summer 2008, you do not need a passport. You can also cruise to the Caribbean (except Barbados), Mexico and the Bahamas without a passport. For any of the small ship cruises that sail only in Alaska, you do not need a passport. The Department of Homeland security expects to announce the new date for requiring passports for all travel outside the US later this spring.

Yes. All you need is a passport.

All travelers need a passport, including babies.

pretty unusual question, if Alaska is part of usa, why would they do that Actually, you might. Because some Alaskan cruises port in Canada which would require a passport.

Cruises that do not begin and end in the U.S. will require a passport when you leave the U.S. For citizens of other countries the same thing applies.

At the moment, US citizens are not required to have a passport to travel to Mexico and the Caribbean by sea. (They must have a passport to travel by air.) You do, however, need a government-issued photo ID (such as a drivers license) and a certified (raised stamp) copy of your birth certificate. At some time in the summer 2008 (per the latest ruling from Homeland Security -- this could change.... again), all US citizens will need a passport to re-enter the US by any means of travel -- sea, air and/or land.

Within the US, on closed loop cruises.

Yes they do. Hawaiian cruises are spectacular, you should also be able to snorkle too. Hawaiian cruises stop at several islands including Jamaica, Bahamas, and the Virgin Islands. You will need a passport to visit these ports so make sure you bring it with you in order to see the islands.

Check with Carnival's website. If I remember correctly, you can use either a passport or your driver's license and a birth certificate. I've taken three cruises with Carnival and I've always used a passport.

yes, ALL individuals need a passport to enter the United States.

Obviously you need a passport.. No you don't. Picture ID is all that is required.

No, when travelling in the US you don't need a passport. All you need is a valid ID. You will stay within the United States which does not require an Internal Passport.

Yes that's all you need

All of them. A passport is needed always when you are leaving the country.

No you don't need a visa. Australia is part of the commonwealth for the UK so all you need is your passport.
