If you tend to get seasick, cabin location is really important. It is a question of engineering, really. The lower and more central you are in a ship, the less roll and sway you will feel. Even if you choose a balconied stateroom, choose the lowest level and the most midship one you can find. The higher decks and cabins at the very front (forward) or back (aft) of the ship will rock and roll the most.
Costa started the spa cabin trend, but many mainstream lines quickly followed suit. The concept is simple: Spa aficionados pay more for cabins decked out in Asian-inspired Zen decor that come with extra amenities, ranging from fancy showerheads and specialty bath products to fluffy bathrobes, yoga mats and healthier room service menus. Spa cabin residents are granted free access to spa restaurants (such as Celebrity s Blu or Costa s Ristorante Samsara), complimentary passes to spa pools and sauna/steam room areas, and may get free, discounted or priority spa treatments and fitness classes. And you do not always have to book a huge suite; on Holland America, several inside cabins have been designated as spa cabins with all the associated perks.
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.
A concierge can take care of all those annoying practical matters you need to tend to on a cruise: making dinner and spa reservations, booking shore excursions, making requests of the front desk. Their services are included in the price of many suites, and on some ships the concierge has a desk in an exclusive concierge lounge where suite guests and high-level past passengers can snack, drink and relax in private. Concierge-level cabins may also come with in-cabins amenities including welcome drinks, fruit baskets or afternoon canapes.
