I really enjoy the Cunard Line, I am English by birth and American by choice. I choose Cunard because they provide Dance Hosts for the single ladies for any length cruise. The Queen's room dance floor and Orchestras are so perfect for Ballroom Dancing and themed parties.
The service is excellent from white gloved afternoon tea to breakfast in bed. Their dining rooms are elegant and comfortable. If that is not your style you can eat in the Buffet.
The shows are always first class entertainment and there is a Single's Club, with daily meetings for everyone to get together
