In order to set the pricing many cruise lines will divide each cabin type into sub categories. For example a balcony cabin may be divided into sub categories such as B1, B2, B3, B4. In most cases the cabin size and features in a sub category is the exactly the same. The only difference is usually the location of the cabin on the ship. Please look for the notes on the category descriptions to determine if there is a difference in size or features between the subcategories.
If scenery is important to you, take a good look at your cruise itinerary before selecting your cabin, specifically if you are choosing an outside or balcony. On a roundtrip Caribbean cruise or a transatlantic crossing, for example, the side of the ship you are on does not really matter. If, on the other hand, you are doing a one-way sailing (such as a southbound Alaska cruise or a trip from Barcelona to Rome), you might want to consider choosing a cabin on the side of the ship that faces the land. Sometimes the views can be breathtaking, and you would not get those views from the cabins that face out to the open sea.
Other pitfalls include service areas adjacent to or above your stateroom; show lounges or bars adjacent to, above or below your stateroom; and self-service launderettes across from your cabin. Other cabins that can be problematic are those that are situated low and at the back (because of their proximity to engine noise, vibration and anchor) or low and forward (because of bow thrusters).
For many travelers, the decision on what size cabin to get is directly related to price. Who would not go for the huge suite if price were no obstacle? Yet it can be tricky to decide whether a balcony is worth the upgrade from a standard outside, or which suite to choose. Here are a few size-related considerations to take into account.
