We travelled the transatlantic route with QM2 and the Baltic route with QV. Both with our daughters 22 and 17 years old. First they were a little bit "nervous" about it (different language) but they really, really liked both tours.
They were "the stars" during the transatlantic cruise, because our daughters were the youngest guest on board and everyone recognized them and said "Hello Hannah and Lea".
There were a lot more younger people and childen during the Baltic cruise and it was fun also.
By the way my youngest daughter said yesterday that she misses Cunard and all of the stuff and guests so much. Expecially "Do you want more tea....more tea?"😄
