Booking connecting rooms on a cruise, defined as adjoining cabins with an interior door, allows families, larger groups, or couples to share adjacent lodgings while cruising.
Connecting rooms provide privacy while allowing easy access between rooms, particularly beneficial for families with young children or groups traveling together who wish to socialize or keep an eye on one another. Historically, this feature was primarily found on larger cruise ships, but its convenience has led to increasing availability across the industry.
