About StayOnboard

Stay onboard. Keep sailing.

Why we built it

Back-to-back cruising — staying aboard the same ship as one voyage ends and the next begins — is the best-kept open secret in travel. It's how people turn a week at sea into a month, and for a growing number of retirees and remote workers, into a way of life. But cruise lines sell every sailing as a separate, unrelated reservation. Finding sequences that connect on the same ship, the same day, at the same port has meant browser tabs, spreadsheets, and hours of cross-referencing — followed by the quiet anxieties: will I have to change cabins? Is this combination even legal?

StayOnboard exists to delete that work. Our chain engine finds every seamless same-ship connection and draws each one as a simple visual timeline. It checks stateroom-level availability across legs so you know when the identical cabin is open on every sailing — unpack once, stay for weeks. And it runs every chain through a Passenger Vessel Services Act validator, silently removing combinations a cruise line would be forced to cancel. The guides share the research behind all of it, free.

How we make money

StayOnboard is free to use, with no accounts and no paywalls. When you're ready to book, each leg of a chain hands off to our licensed travel-agency partner, and if you complete a booking we may earn a commission from that partner. The commission comes out of the travel agency's margin — it does not increase the price you pay. That's the entire business model: we only do well when we help you actually take the trip.

Commissions never influence what you see. Chains are ranked by feasibility — length, cabin continuity, itinerary variety, availability — and compliance warnings are never softened to protect a sale.

Independence

StayOnboard is an independent service. We are not affiliated with, endorsed by, or sponsored by Carnival Cruise Line, Royal Caribbean, Princess Cruises, or any other cruise line. Ship and brand names appear solely to identify sailings, and all trademarks remain the property of their owners. Itinerary details and pricing are provided for planning; always confirm specifics at the time of booking — schedules and regulations can change, and our guides are general information, not legal advice.
