For some reason, most cruise lines assign their nicest and most expensive cabins to the highest decks, usually just below the pool deck (most likely because if you have a window or balcony, you have a more sweeping vista). Still, it is the pool deck that often causes the most noise problems, so if you do not want to hear scraping chairs at the crack of dawn or yee-hawing pool parties until the wee hours, go down a level. In fact, when it comes to noise, the best bet is to select a cabin that is both above and below other cabins.
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.
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.
Oceanview cabins: These cabins are like inside cabins but usually have a port hole or window. A window is much more desirable than a porthole because the porthole can be difficult to look through. Windows will vary in size and some cabins will even have full floor to ceiling windows. Most window sizes for oceanview cabins are about 4 feet by 3 feet. Be sure to read the cabin description carefully to determine if there is a different type of window. Windows can not be opened. Expect to pay $150 to $250 a night for an oceanview.
