Zenith and Horizon have some of the largest cabins in the mid-price range of ships, all boasting terrific amenities. Standard inside and outside staterooms are 172 square feet, with ample closets, small refrigerators, color TV with CNN, bathrobes and good-size bathroom with shower. On these ships, you can safely book a lower grade stateroom and still get all the perks. Those who adore cabins with private verandas, however, won’t find them on these ships. Category 7 staterooms have views obstructed by lifeboats. Suites have butler service, marble bathrooms, and personalized stationary.
