Dancing downhill during ocean swells was challenging but manageable. The Staff Captain came up to me and hinted that the trick was to stay near amidships on the dance floor during the swells. The bands played music suitable for West Coast Swing, Foxtrot, Cha Cha, and Rumba with an occasional Waltz, Tango or Quickstep thrown in. The Romantic Swing Trio was particularly friendly and accommodating in playing enjoyable dance music. At the Southernmost extent of the trip, it never got completely dark, which gave the feeling of dancing at sunset even after midnight.
Most ships carry a theatre arts or cabaret performance couple as part of the entertainment team.
Since I much prefer watching ballroom dance to theatre arts dance performances, this was a much-appreciated feature of this cruise. There were two dance classes offered, neither of which we attended. The dance host staff included one British gent and two Americans. One of the Americans got the job by being a friend of the Cruise Director. He only learned ballroom dancing a few years back in order to get a dance host position.
