What is the fastest way to go from Italy or Spain to buenos aires by ship?

Question

I could take a cruise ship but do not want to spend to much time on travelling. Flying has become a pain nowadays. After spending 3 weeks or so in Buenos Aires I would like to return using the same (or a similar) route.

by ship

Answer 2

Many freighters that traverse the world make space for passengers.  They have their own cabins and the I read that the meals are very good.  However, they are very expensive and they take a lot of time.   There are several websites on freighter travel.  Interesting way to travel if you have time and money.  The plane is your best bet despite the pain.
