Cabins are priced based on location on the ship. Typically cabins on lower decks are less expensive. Typically cabins midship (in the middle part of a deck) cost higher. Balcony and Suite cabins on the very aft of the ship can also be more expensive than other cabins.
Since cruising has become a popular family vacation, more new ships have built "family accommodations" into the actual design. These are often suites, each with a separate room for the kids -- sometimes a small alcove with bunk beds, sometimes an entire adjoining cabin. Families and groups can also take advantage of regular staterooms with third or fourth berths found in pullout sofas or pull-down bunk beds (called Pullmans). If you are going to squeeze your whole troupe into one cabin, make sure the space is big enough to accommodate the lot of you ... and all your belongings.
Very few ships actually have cabins dedicated to solo travelers. These will have sleeping space for one and can be quite small. The studio cabins on select Norwegian ships are the most famous example of this: The 100-square-foot staterooms each contain a full-size bed, nifty lighting effects and a large round window that looks out into the corridor. If you are a solo traveler, you will want to price out the cost of a solo cabin (usually somewhat higher than the double-occupancy rate of a similarly sized stateroom) compared to the cost of paying the single supplement (an extra fee tacked on if there are not two people in a cabin; the price can come out to as much as double the regular rate) for a standard cabin. And book early, as solo cabins sell out quickly.
Balcony cabins: These cabins are better, and more expensive, than oceanview cabins because they typically have full glass sliding doors that lead to a balcony. The balcony allows fresh air and light into the cabin and also may have additional chairs or loungers. Balconies tend to be separated by dividers which give some sense of privacy, but be aware that most balconies are not fully private and can be viewed from above or by the cabin next to you. Balconies on new Norwegian Cruise Line ships and Princess Cruise Line ships tend to be smaller and more narrow than balconies on other ships. We will list balcony size in the cabin description. Carnival offers what is called a "Cove Balcony" on some of their ships. These balconies are very popular because they sit lower on the ship (closer to the water line). Expect to pay $200 to $400 a night for an balcony cabin.
