Inside cabins: These cabins are usually the lowest price. Typically they will have twin beds that convert to a queen size, a private bath with a shower, a closet for hanging clothes, a dresser and a television. These cabins do not have a window to let natural light in. To help give the occupants an impression of having a view, some inside cabins have a virtual view. That means there is a large screen that displays outside views. Expect to pay $100 to $200 a night for an inside cabin.
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.
Pay attention to the unique cabin setups on your ship, as they are not all created equal. Disneys four cruise ships, for example, have large standard staterooms designed to accommodate families. Even inside cabins may have a sleeping section that can be curtained off from the living area along with a split bath system. (One bathroom has the shower/tub and sink, another a toilet and sink.) Carnival is also known for having larger-than-average standard cabins, while Silversea, Regent Seven Seas Cruises and Seabourn ships feature all-suite accommodations. Norwegian Epic cabins sport the "new wave" design, with curvy walls and separate rooms for showers and toilets; sinks are located in the main cabins. As mentioned earlier, cabins at the very front and back of a ship often have different layouts than the cookie-cutter cabins that run the length of the ship.
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.
