A first Royal Caribbean sailing can feel less like boarding a ship and more like stepping into a floating resort. The largest Oasis- and Icon-class vessels have sprawling public areas, restaurants, shops and entertainment spaces; the article points to Central Park, with more than 20,000 live plants, as one example of how easily passengers can lose sight of the fact that they are at sea.

New cruisers should also plan for less personal space than they may find at a hotel. Royal Caribbean Blog notes that a standard ocean-view stateroom on Anthem of the Seas is about 182 square feet, including its bathroom, compared with more than 376 square feet for a standard king room at Hilton Cabana Miami Beach Resort. Cabin-door decorating is another common cruise tradition, though passengers should check which materials are permitted before packing decorations.

Practical ship routines can take adjustment, too. Royal Caribbean requires every guest to complete a muster drill before departure, typically by viewing a safety video and checking in at an assigned muster station. Onboard purchases are generally charged to a guest's SeaPass account, while cash settlement is possible but can require payments or a card once a spending limit is reached.

The guide also advises travelers to expect busy elevators, pool decks, buffets and embarkation areas, particularly as the line says demand remains strong. Some items familiar at home—including irons, clothes steamers, power strips, multi-plug outlets, marijuana and firearms—are prohibited, so reviewing the cruise line's restrictions before packing can help avoid a port-day surprise.
