My dad used to work on the container freighters and I had the chance to go with him once. The accommodations were pretty good and passengers typically ate in the officers dining room. Though I suppose eating with the sailors could be even more interesting! Anyway, having been in the holds, especially on a ship that was transporting a few containers full of cured animal hides - the stowaway thing would probably suck more than a little!
It was a great way to see part of Asia with a lot of time to oneself between ports. The downside is that if you are traveling by one boat, you may not get a whole lot of time in port as those things are loaded and unloaded pretty quickly!
