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.
Be sure to give us a report!
