I especially love the dancing when cruising on the Cunard ships, Queen Mary 2, Queen Elizabeth and Queen Victoria. All three have beautiful ballrooms, called the Queen's Room. On several of my Cunard cruises, most recently a two-way transatlantic cruise on QM2, the cruise director has hosted Sequence Dance sessions in the Queens Room. I badly wanted to join in but not knowing any of the patterns, I had to sit and watch. Sitting still while dance music is playing is hard for me so I vowed  to learn these dances so I could participate in the future.
