Why do Some Cruise Lines Charge the Same Rate for Babies as Adults? Though babies and toddlers clearly do not consume nearly as much food and drink, nor partake in the same activities as their parents, babies still create extra cleanup and housekeeping work that the ship's crew ultimately must take care of.

Many parents are surprised that cruises charge for infants, but it boils down to manifest limits and safety regulations. Every person on a ship, regardless of age, must be accounted for in the ship's maximum capacity and life-raft manifest required by international maritime law. This means an infant takes up a "soul" count that could otherwise be occupied by a full-paying adult. Additionally, cruise lines incur costs for infant-specific services, such as providing cribs, high chairs, and specialized cleaning. Even if an infant doesn't eat the buffet food, they use the ship's infrastructure, including the desalination plants and waste management systems. While some lines like Royal Caribbean offer "Kids Sail Free" promotions, you will almost always still have to pay mandatory port taxes and government fees for the baby. Charging for infants also helps the cruise line manage the ratio of staff to passengers, ensuring they have enough crew members to handle emergencies for every passenger listed on the manifest, no matter how small.
