When trying to determine how much cabin you can afford, do not forget to factor in the cost of the rest of your trip. If you have to spend a lot on airfare, pre-cruise hotels and activities in port, you might not be able to afford the fanciest suite; if you are using frequent-flyer miles or do not need to book a hotel, you will have more money for cruise fare; the money you save on airfare can be used to spring for a nice stateroom. Or, look for value-added perks from cruise-line and travel-agent promotions. Offers for complimentary onboard cash, prepaid tips or included airfare can free up some money to pay for other vacation expenses.
Some cruise travelers prefer their cabins to be near to (or far away from) specific areas of the ship. Sun-worshippers might prefer an upper-deck location close to the pools and sun decks, while partiers might want easy access to midship entertainment hubs. Travelers with mobility concerns may prefer a stateroom close to a bank of elevators.
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.
Exception: Carnival has several cabins which are classified as inside cabins but actually have a french glass door which allows light into the room (no balcony, but the door can be opened). Carnival also has some cabins that have a window, but because the window has an obstructed view (that means there is a railing or object in the way) it is listed as an inside cabin. Royal Caribbean has some cabins that have a window but look out over an inside promenade area. These are called "promenade staterooms".
