Mr and Mrs Robinson have planned to take their daughter on a cruise. Their friends, the Wilsons, experienced "cruisers", call, but are not very encouraging, and somewhat damp the joyous Robinsons. They are completely discouraged when their daughter arrives to announce her engagement, and consequent refusal to go cruising. Finally, Mr and Mrs Robinson cancel the cruise, and instead arrange to go to Bognor, where they are sure of enjoying their holiday.
