Royal Caribbean's Quantum class ships, including Anthem of the Seas, are best known for their innovative use of technology, but there are new cabin categories on these ships, too. This 575-square-foot setup ingeniously combines three cabins: a junior suite, an ocean view with balcony, and an inside studio. They all share a vestibule, so that you can close the entrance to the hallway but keep your cabin doors open, giving it the feeling of one sprawling suite. There's room for eight to 10 guests. Bonus: You get three bathrooms.

On some Royal Caribbean ships, including the new Harmony of the Seas, there’s a category type that's perfect for a big group who wants an affordable option. These large inside rooms can sleep up to six. Two twins convert to a Royal King, and there’s also a pullout double-size sofa bed and two Pullman-style bunks. The size varies: from 260 square feet on Harmony up to 324 square feet on the line’s Freedom-class ships.

On Norwegian Cruise Line’s newest ships, including the Miami-based Norwegian Escape, families of up to five can stay in a stateroom with views through a large picture window. A privacy curtain separates the bed area from a double sofa bed, with a Pullman-style bunk above. In the bathroom, you’ll find double sinks and a tub. Plus, there's a second wardrobe for storage. The rooms are conveniently located near the Splash Academy, making them even more perfect for families traveling with young kids.

A first for Holland America Line, these family-friendly staterooms on the new Koningsdam are designed to sleep a family of five. You'll find two lower beds which can convert to a queen, a sofa bed which accommodates two people, plus an upper bunk. The cabins come with two bathrooms — one with a tub and the other with a shower — and there's lots of extra closet space.

These affordable cabins on select Carnival Cruise Line ships sleep up to five, with two twin beds, upper bunks, and a single sofa bed. On recent Dream-class ships, they come with two bathrooms (one with a small tub and the other with a shower). On the just-launched Carnival Vista, the Deluxe Family Ocean View Staterooms are located in Family Harbor, a new concept that includes a shared family lounge with concierge service, 24-hour snacks, movies, and video games.

Not surprisingly, all staterooms on Disney Cruise Line’s ships are designed with families in mind. We like this category in particular because you get 300 square feet to spread out. With the privacy curtain, you can separate the queen bed from the single sofa bed and pull-down bunks. Most of the rooms include 1 ½ baths — a toilet and sink in one and a tub with shower and sink in the other.

Looking for qa family-friendly suite, and willing to pay for the space? In these fancier Disney Cruise Line accommodations, you get more than 600 square feet of hangout space and two bathrooms (one with a whirlpool tub). The suite sleeps five, with a separate master bedroom and a living room which has a double sofa bed and Pullman-style bunks. Perks include a wet bar stocked with water and sodas, plus all sorts of VIP concierge services. For a truly over-the-top stay, book the even larger Royal Suite.
