All rooms are not created equal on cruises, and they come down to more than just inside, oceanview, or balcony choices. Traveling with a large group? Look into booking a cruise with suites, which can be much more affordable to a family of four, for instance, than getting two standard staterooms. This can amount to savings of a few hundred dollars or more. On the flipside, solo travelers shouldn’t be forced to stay in a room made for two or four people. Lines like Norwegian (the first to do so) actually offer 100-square-foot studios, which also include access to the exclusive Studio Lounge. Not only does Norwegian not penalize its single passengers, but it rewards them with a cheaper rate and a shared private area where social solo sojourners can meet, mingle, or just relax. MSC, for its part, allows kids to cruise free on select sailings, which is a huge instant savings and could possibly seal the deal for travelers with the whole clan in tow.
