A lot of people remark that cruising is not for them when they have not ever tried it! Comments like, “I would be bored,” there is so much to do if you wish to join in so it would be hard to be bored. “I would feel trapped” even the smaller ships of i.e. Fred Olsen, are very spacious and have plenty of places for a walk.
I feel the best cruise to start with and as a taster are the Norwegian Fjords, so beautiful and the best way to see the beauty is from the fjord itself (on a cruise ship of course).
