So which did you prefer, between the two modes of travel?
They are two completely different experiences.
The plane is to get you from Point A to Point B quickly.
The ship is a holiday in itself.
The only problem with the ship is that it takes so long to get where you are going that you have to reduce the amount of time you spend in the place you are visiting (assuming that you don't have unlimited holiday time).
Also, if you take the ship both ways, there are no limits on how much luggage you can carry on.
