Of course they are! Cruises are fun for kids of all ages, and there are plenty of activities to keep your toddlers entertained. Kids under the age of 3 can enjoy Toddler Time at the ship's playroom, where they'll be able to play with educational toys and interact with other kids around their age.

Whether a cruise is "worth it" with a 2-year-old depends heavily on your choice of ship and your expectations. At age two, most children are not yet "potty trained," which is a crucial distinction; most cruise ship pools prohibit swim diapers, meaning your toddler might be restricted to specific "splash pads" designed for un-potty-trained kids (common on newer Royal Caribbean, Disney, and Carnival ships). On the plus side, cruises offer a controlled environment with easy access to food and your cabin for nap times, which is much easier than trekking through a city. Many lines also offer "nursery" services for a small hourly fee, giving parents a much-needed break. While the child likely won't remember the trip, the ease of having everything in one place—combined with the high-quality entertainment and kid-friendly staff—often makes it a much more relaxing "parenting-on-the-water" experience than a traditional road trip or hotel stay.
