Beautiful trip. I avoid those that feature Mickey Mouse and Carnivals, and so on, but I have had an enjoyable experience with Norwegian. I hear rave reviews about Holland.
I am trying to split the difference between hobby and practicality. It practically runs, though finding parts is a bit dodgy, but thanks to the internet I think I've located a new wiper motor. I've always wanted to travel south India by rail, preferably narrow gauge, perhaps, but this is as close as I'm going to get for a while.
