Find Your Cruise
The best advice is use the review section & go through each cruise line to find your particular taste, needs & wants. Formal/informal/ kids/no kids/ big & brash/ small & select/etc. etc. Only you know those answers...Wilba.
Slightly longer but how about P&O Arcadia 10 days to Canaries from Southampton sailing on 21 Oct. Adult only ship so no kids.
