"Do you have to check bags on a cruise" is an interrogative sentence, functioning as a noun phrase. It relates to the question of whether luggage must be checked in before boarding a cruise ship or if it can be carried on by passengers.
Deciding whether to check bags on a cruise requires understanding cruise line policies, packing restrictions, and potential fees associated with checked baggage. Historically, checking bags was the norm for air travel, influencing cruise line practices in the early days of cruising. However, as technology evolved and carry-on luggage became more common, cruise lines adapted to offer passengers the convenience of keeping their belongings with them throughout the cruise.
