I agree with Collette - please spend the money and get a cabin.

The trip from Patras to Ancona is long - at least 24 hours, even on a fast boat. When I did it, in early April 2000, there were very few passengers, and for the price of a single bunk I had an entire 4-bed cabin (brand new, with its own tiny but efficient bathroom)to myself.

While the airplane style seats did not look uncomfortable, they were crowded into a small area near a lounge that was always noisy with electronic games and canned music.

Cabins did not seem terribly expensive - especially if you are able to get a large one for the price of a couple of bunks.
