Your room on a cruise ship is called a cabin (or stateroom) and is akin to a hotel room, but typically much smaller. Choosing a cruise ship cabin can be fun and challenging at the same time, and not just a little bit frustrating on occasion. You need to discover the cruise deck plan first. Cabins fall into different types or "categories," and some cruise lines will present as many as 20 or more categories per ship. Before you get overwhelmed, it is helpful to remember that there are essentially only four types of cabins on any cruise vessel.
Suite:A suite is a premium cabin on a cruise ship. It is usually much larger than a balcony and includes more perks. Suites typically have a full bath tub, large shower, larger closets, larger balcony, larger TV, and butler services. Expect to pay $400 to over $1,000 a night for a suite.
Do you need a balcony? Cruise travelers who spend all their time in the public areas -- sun decks, lounges, restaurants -- or on shore may be perfectly happy with standard-size cabins and no private outdoor space. Those who love to avoid the crowds and lounge quietly on their own verandahs or have private room-service meals outdoors will surely want balconies. Do not forget to take your itinerary into account; on a chilly-weather cruise, you might not be spending too much time outside, so depending on how much space and light you need, a balcony might not be worth the splurge.
Exception: Royal Caribbean and other cruise lines will also use sub categories to distinquish between how many occupants the cabin will sleep. Therefore a cabin that can sleep up to 4 people will be a different sub category from a cabin that sleeps only 2 people.
