To reduce motion sickness, choose a stateroom in the middle of the ship on a lower deck. You will feel any sway of the ship less in this section. Although it may seem counterintuitive, if you're worried about seasickness on a cruise, book a stateroom with a window or a veranda.

To minimize the effects of seasickness in 2026, the best location for a cabin is on a lower deck toward the middle of the ship (mid-ship). Think of a cruise ship like a seesaw: the ends (bow and aft) move significantly up and down, while the center remains relatively stable. Lower decks are closer to the ship's center of gravity and the modern hydrodynamic stabilizers that most large 2026 vessels use to counteract rolling motions. If you are sensitive to movement, avoid "Forward" cabins on high decks, as these experience the most dramatic swaying. Experts also recommend booking a cabin with a balcony or a large window on these lower-middle decks; being able to see the natural horizon helps your brain reconcile the motion your body feels with what your eyes see, which is often the fastest way to quell nausea. If you're in a public area, the promenade decks (usually located around Deck 4 or 5) provide the best balance of stability and access to fresh air.
