Things that aren't included in the basic cruise fare are airfare, shore excursions, alcoholic beverages, spa treatments, souvenirs and casino games. The cruise you choose will also affect your total cost. A longer world cruise vacation costs more than a shorter one, of course, but the cruise line matters, too.

While your Princess Cruise fare covers your cabin, main dining, and basic entertainment, several "extra" costs can add up quickly. In 2026, you generally must pay for Alcoholic beverages, sodas, and specialty coffees unless you have a "Plus" or "Premier" package. Gratuities (Daily Crew Incentives) are also a mandatory extra charge, typically around $17–$19 per person, per day. Other out-of-pocket expenses include Wi-Fi access, specialty restaurants (like the Crown Grill), shore excursions, and spa treatments at the Lotus Spa. Even some "premium" onboard activities, like the Ultimate Ship Tour ($150) or access to the adults-only Sanctuary sun deck, require a fee. To avoid being "nickeled and dimed," many travelers opt for the Princess Plus package, which bundles Wi-Fi, gratuities, and a drink package into a flat daily rate, providing a more "all-inclusive" feel to the vacation.
