What is included in the cruise fare?

Standard cruise fares include your cabin, onboard meals at main dining venues, most non-specialty entertainment, use of pools and common facilities, and transport between ports of call. Gratuities, specialty dining, alcoholic drinks, shore excursions and onboard spa services are typically billed separately.

How far in advance should I book this cruise?

For popular sailings, booking 6–12 months ahead typically gives the best cabin selection and fares. Last-minute discounts can appear 30–60 days before departure when the cruise line wants to fill remaining cabins on Britannia.

What documents do I need to board?

Most international itineraries require a passport valid for at least six months beyond your return date. Closed-loop sailings that depart and return to the same U.S. port from Southampton may accept a government-issued photo ID plus a certified birth certificate for U.S. citizens — always verify with the cruise line.

Can I change or cancel my booking?

Change and cancellation policies depend on P&O Cruises's fare type and how close you are to departure. Refundable deposits typically allow changes up to the final-payment date without penalty; closer to sailing, cancellation fees scale up. Review the specific fare rules before booking.

What is a 21-night cruise like?

A 21-night cruise balances relaxing sea days with active port days. You can expect a mix of onboard programming — dining, entertainment, spa and fitness — and multiple shore excursions from Britannia. Pack for both formal nights and casual deck days.
