Things to consider before Royal Caribbean cruises booking
You'll need a valid passport, an official copy of your birth certificate, as well as a driver's licence, or other government-issued picture identification as a U.S. citizen. Passports must be valid for at least six months as it is required for cruises departing from international ports. The name on your reservation must match the name on your passport or other legal documentation of nationality.
Smoking is permitted only in certain areas. It's prohibited in cabins and balconies, and violators will be charged a penalty.
For drinking, on sailings departing from North America or the United Arab Emirates, you must be 21 years old to consume alcohol. On sailings from South America, Europe, Asia, Australia, and New Zealand, the drinking age is 18.
There is no specific dress code during the day, and individuals dress casually. There is an official dress code in the evenings; however, it only applies to passengers entering the main dining area.
All Royal Caribbean cruises only accept US dollars as their currency. All ships operate on a "cashless system," with all onboard purchases instantly credited to your account. You'll be given a SeaPass card to use to make purchases.
