Ultimately, the decision between inside versus outside cruise cabins comes down to whether you want a window. If you absolutely must have natural light or a way to see your external surroundings from your room, an outside cabin is for you.

The primary difference between an inside and an outside (oceanview) cabin is the presence of a window and the resulting exposure to natural light. An inside cabin is located in the interior of the ship's deck and has no window, porthole, or balcony. These are almost always the most affordable rooms, making them ideal for budget-conscious travelers or "power cruisers" who only use their room for sleeping. Because they are completely dark when the lights are off, many guests report having the best sleep of their lives in them. In contrast, an outside cabin features a window or a porthole that provides a view of the sea and allows daylight into the room. While the square footage and amenities (like the bed, TV, and bathroom) are usually identical to inside cabins, the window makes the space feel significantly larger and less claustrophobic. An outside cabin is perfect for those who want to wake up and immediately see their destination or the current weather, though they do come at a slightly higher price point and are often located on lower decks closer to the waterline.
