But the reality is that cruise ships, like hotels, come in all sizes and standards, and are designed to appeal to a wide range of budgets and tastes.
The right ship
Some ships are perfect for honeymoon couples and youngsters in search of a
lively holiday; others are better suited to travellers with youngsters in tow or
to older people seeing the world a deux.
With their fantastic range of "floating resort' facilities, the Caribbean's
collection of 2,500-passenger-plus mega-ships provide the ultimate all-action
arena for young (and the young-at-heart) party animals.
But those who like to take life a little more gently may find a Mediterranean
cruise aboard an older, more traditional ship more to their taste. Prefer a
taste of adventure? Try a sailing ship, or an ice-hardened adventure vessel. Or
a cruise to the glaciers of Alaska,
America's "last Wilderness".
Most of these ships will offer an element of luxury, in the shape of state-of-the-art facilities, nicely cooked meals, attentive waiter service, cosy bars and well stocked libraries.
True Luxury
But - and it's a big but - there's a world of difference between the little
luxuries of ordinary cruising and true luxury cruising. If it's the real McCoy
millionaire-on-sea treatment you're after, there are only a handful of cruise
lines which really come up with the goods.
For the essence of real luxury cruising is that it provides four essential things; space, exclusivity, top quality service, and lack of hassle.
What you get
Passengers booking a luxury cruise can expect to be greeted on arrival with a
complimentary bottle of champagne; to have a spacious cabin with a walk-in
wardrobe, an elegant bathroom, a well stocked mini-bar and 24 hour room service
- with full in-suite dining available during restaurant hours.
They never have to queue to get food and drink, and never have to wait to use equipment in the gym or be seated in the dining room because such ships have more than enough space to accommodate everybody onboard in comfort. They may be able to dine when and with whom they please, and they can look forward to travelling in small groups on shore excursions - which should feature the most exclusive and up-market hotels.
Above all, passengers paying luxury ship prices can expect excellent, unobtrusive service and a truly cash-free environment, with some top luxury ships offering complimentary drinks and wine at dinner.
The ships
The small luxury ships owned by Seabourn
Cruise Line and Radisson
Seven Seas Cruises are the most exclusive in the world purely in terms of
their size.
'Radisson Seven Seas Cruises' exquisite 180-passenger vessel Song of Flower and Seabourn Cruise Line's Seabourn Pride, Seabourn Spirit and Seabourn Legend, at 200 passengers apiece, are next largest.
But the largest ship in this category is Radisson Seven Seas Cruises' 354-passenger luxury twin-hulled Radisson Diamond.
At the other end of the size scale, the prestigious Fielding's Cruise Guide also grants six star status to three larger ships - Crystal Cruises' 960-passenger vessels Crystal Symphony and Crystal Harmony, and Seabourn Cruise Line’s 740-passenger Seabourn Sun.
Luxury cruise liners
Crystal Cruises launched its first ship in 1990, and since then the line has firmly established itself within the deluxe market with the largest Six Star rated fleet in the world. The philosophy of the company is “to re-establish what luxury means in the cruise industry”, on board its two 960 passenger ships.Cunard
is one of the leading cruise lines with a wealth of history and tradition.
Cunard offers a range of itineraries, including round-the-world and Caribbean
cruises, as well as the scheduled transatlantic crossings aboard QE2.
Radisson
Seven Seas was formed in 1995 following the merger of Diamond Cruise of
Finland, and Seven Seas Cruises of San Francisco. It now operates a wide-ranging
and luxury-quality fleet of six star rated small ships, operating port-intensive
itineraries for the sophisticated traveller.
Seabourn
Cruise Line is generally regarded as the most celebrated cruise lines in the
world and is positioned at the very top end of the luxury market. It offers a
level of service second to none, setting Seabourn in a class of its own.
Seadream Yacht Club
Rated above all contemporary cruise lines in the 2003 edition of the
authoritative Berlitz Guide to Cruising, SeaDream 1 & 2 accommodate around
90 passengers on each voyage, the crew to passenger ratio is averagely 1:1. From
Bulgari toiletries to Pommery champagne, Belgian linen to the Asian Spa, from
the Top of the Yacht Bar to the Balinese Sunbeds, SeaDream Yacht Club are the
perfect antidote to conventional cruising.
True luxury ships do not follow set schedules but offer worldwide itineraries with the emphasis on the offbeat - Crystal Harmony, for example, has a new cruise of Japan and China among her itineraries this year, while the Seabourn Pride has cruises of the Chilean Fjords in her line-up.
Such ships are aimed at people who seek not only an interesting travel itinerary but also a genuine insight into the places they are visiting and the broader world about them.
Expert lecturers in the fields of history, geography, archaeology and other disciplines are regularly invited on board to give guests talks and lead them on walks ashore.
And some of the world's greatest stars and performing artists have been spotted on cruise ships - either talking about their craft or simply enjoying a few days away from the pressures of stardom.
For example, the relaxed combination of a casual, sporty atmosphere and top quality service attracted rock icon David Bowie to the five star rated sailing ships of Windstar Cruises a few years ago.
No doubt Bowie was impressed by the music systems installed in every cabin - with speakers aimed inwards towards the bed so you just hear your own music, no-one else's. Cunard's five star liner QE2 is the greatest star-grabber of them all - Nelson Mandela and Elizabeth Taylor have both been on board.
Seabourn - is the not surprising choice of computer billionaire Bill Gates and Donald Trump; Silversea, meanwhile, has played host to the likes of Charlton Heston and Richard Dreyfuss.
But don't be intimidated into lashing out on more designer wear than Joan Collins - smart casuals in natural fabrics are fine for daytime.
In the evening, splash out with anything from a cocktail dress to a full ballgown - but keep jewellery discreet
Best of the rest
If your budget doesn't quite match Bill Gates', and you can't run to a truly
top-of-the-range ship - or you feel a small luxury vessel would be simply too
confining - try booking a top cabin on one of the big ships.
Celebrity Cruises' five star Galaxy and Mercury have beautifully designed top suites with large balconies and butler service, as do the state-of-the-art Grand Class vessels of Princess Cruises.
Holland America Line has some pretty top suites and an old fashioned charm to its ships, which feature lovely flower arrangements and priceless museum displays.
Big ship cruising won't give you the exclusivity or standards of service available in the top, small luxury ships. But it will give you access to an enormous range of facilities, with the option of heading back to your suite for a romantic dinner in the evening - or eating at one of the many restaurants your floating resort has to offer.
