Hi there Jean and welcome to Cruisemates.
Unfortunately every cruise line offers different experiences to different people depending on their own expectations, so whilst I cannot make any specific reccomendations for you, I can fully reccomend the following website which seems to have excellent information about all the cruiselines, ships, destinations & so on, and therefore may be of use.
Cruise directory with thousands of cruises, deals, offers and impartial advice for your holidays from Choosing Cruising
Hopefully you should be able to access the co.uk domain.
Happy hunting, and once again, welcome on board.
