Cruising can require a surprising amount of walking, especially as modern ships have grown to become "floating cities." A typical Oasis-class ship can be over 1,000 feet long; a round-trip walk from your cabin at the aft (back) to the theater at the bow (front) can easily be a quarter-mile journey. For an active guest, it is not uncommon to clock 10,000 to 15,000 steps a day just navigating the decks and visiting the various dining and entertainment venues. Furthermore, many shore excursions—particularly in historic European cities or during nature hikes—involve significant walking on uneven terrain or cobblestones. For those with limited mobility, cruise lines like MSC and Royal Caribbean offer accessible cabins with wider doors and ramps, and they provide elevators at every major hub. However, guests are encouraged to bring their own manual or electric wheelchairs if they require constant support, as onboard wheelchairs are typically reserved for emergencies and embarkation/disembarkation. If your itinerary involves "tendering" (using small boats to reach land), you must also be mobile enough to step on and off the boat safely.
