On Carnival Cruises, your cabin is your home. After the day is over and you've had enough fun, head back to your cabin for the night. Whether you choose a minimalist interior, a room with an ocean view, or a luxurious room with a balcony or suite, you'll find yourself well-equipped to end the day. Allow. All staterooms also have a maid on duty at any time of the day or night, attendants for complimentary room service, and other in-house perks.
