What each cruise line actually lets you bring aboard
Dress codes, alcohol and soda allowances, prohibited items, luggage timing and arrival windows differ more between lines than most people expect, and the differences are the part that catches you at the security scanner. Every rule on these pages was read on the line’s own policy page and carries the date it was read. They compare published policy and the embarkation-day experience — not food, entertainment or price, which this site has no evidence for.
