For many first time cruisers, the decision of which category of cabin to choose is a bewildering and complex decision. A good first step might be defining terms in the hopes of clarifying the options.
Most cruise cabin layouts can be summarized into four different cabin types:
Inside cabin

Interior or inside cabins do not have a window or ocean view or any natural sunlight. Many inside cabin decorations feature a window treatment to give passengers the illusion that a view is available. The inside cabin is the least expensive option but still affords the budget traveler all of the same out of cabin amenities enjoyed by other passengers.
Outside cabin 
The standard outside or ocean view cabin has either a porthole or full picture window from which the passenger can look out. Views can vary from open water to more interesting sights such as glaciers in Alaska or city views when arriving or departing different ports. Contrary to popular myth, all outside cabins are above the water line regardless of the deck location.
Balcony or Verandah Cabin
A step up from the outside cabin and a cabin category in increasing demand is the balcony or verandah cabin. Most balcony cabins have a large ocean view window punctuated by a door opening out to a balcony or verandah. Balcony size varies according to ship and cabin category. Most standard cabin balconies are large enough for a couple to sit out and read or converse. There is often a small table in between the chairs where a drink or other items may be placed.
Suites
Suites vary in size from Junior Suites which may be slightly larger than a balcony cabin to one bedroom suites which have a bedroom apart from the main area and can be double or even triple the size of other cabins. Many suite balconies are larger than their standard verandah cabin counterparts. Bathrooms also tend to be more spacious than the standard cabins and may have additional amenities such as whirlpool tubs.Full information on cabin types is readily available online, in print, or from a qualified travel agent.Choosing the Right Cabin
Now that we’ve defined terms, we can progress to the heart of the issue. Which cabin is right for you? Without conducting a full interview of your background, I would not feel comfortable in making such a recommendation. However, I can suggest some of the considerations which will assist you in the direction of making the right decision. These priorities include:
Price
Since almost all modern cruise ships are one class, possible budgetary limitations should not preclude choosing a cabin which fits the finances available. In a one class environment, all facilities, entertainment, and dining are equally available regardless of cabin choice
Number of people traveling
A cabin which might be perfectly adequate for a family of two could take on an entirely different perspective by adding up to three additional persons. Choosing one cabin or dividing into two or more is of course, also a budgetary issue. In recognition of the increased number of families taking cruises, some lines have added family cabins which are designed to comfortably accommodate additional persons. Some cabins which are side by side may have interconnecting doors to become adjoining as opposed to simply adjacent. Some ships even offer interconnecting balcony doors in the event that there is not a connecting door between cabins.
Cabin location
Cabins located on higher decks are generally priced higher than cabins located on lower decks. In most cases, most passenger facilities are located on mid to higher decks making the distance from lower decks to pool areas, spas, buffet areas, and other public areas further away. The location issue is minimized by high speed elevators that contract the difference in deck location to a matter of seconds in either direction. On modern cruise ships which are constructed in a modular format, cabins on lower decks are identical in appearance and size to higher deck cabins in the same category. ConclusionMaking the right cabin choice may become easier by recognizing that cruise passengers enjoy the highest level of overall vacation customer satisfaction. Most surveys indicate satisfaction levels in the 95% plus levels. These statistics imply that while cabin choice can enhance the enjoyment of the cruise, it does not in and of itself determine the quality of the overall experience. My recommendation is to review the options available with a qualified cruise counselor who can clarify the options available.
