That is true for SOME countries, but if your cruise takes you beyond European Union countries, the Caribbean, plus a handful of others, American citizens often need visas in addition to their passports and in very few instances does the cruise line handle the process for you.
The costs are spelled out
During my research, I discovered that not only was it difficult to find the cost of the various types of visas a country offered but often the government sites themselves swapped me to third-party sellers for the application process, many with hidden fees.
I’m definitely a do-it-myselfer when it comes to travel planning— and not inclined to pay a service fee when I can do something myself and avoid the fee or save a few dollars.
Wander around iVisa’s website a bit and see if you don’t feel safe, secure, and better informed than when you arrived, better yet, do some cruise dreaming and punch in a few countries in the tool below to see how easy it will be to apply for the countries you long to visit by cruise ship!
