Lucky you! The QE 2 is much beloved by those who know her. I worked at Cunard Line (more years ago than I'll publicly admit, lol) and she was my first ship! Salvador Dali sailed with his two cheetahs booked in a separate suite but they tossed the cats off at the first port because they destroyed the cabin.
I haven't sailed the fjords yet, but I'm sure it will be an unforgettable trip.
Did some of the fjords on QM2 two years ago and I'm planning a voyage to North Cape next year. Alas, not on QE2 (my favourite ship). Via the webcam, saw QE2 in Geirangerfjord yesterday (19th.) Hope you had a good trip.
