My family and I are booked on the V315 starting June 6.
Last September my mother and I did a Norway cruise on the QM2 in September. Generally we had to get up early to see the fjords as at that time of year, it would be getting dark when the ship cruised back through the fjords to depart for the evening .
We enjoyed the scenery of the smaller ports, the larger cities, while scenic, were not quite so exciting.
Choose between the cruises based on which appear to cover the areas you are most interested in seeing.
Maybe I will see you on board in June.
