Best Cruise Price Trackers in 2026: Cruiseplum vs CruiseWatch vs Cruise Radar vs track.cruises

TL;DR: Cruiseplum is the strongest cruise search engine for US bookers. Cruise Radar is the best browser overlay while you shop on a cruise line’s own site. CruiseWatch covers a lot but has documented accuracy complaints. track.cruises is built for tracking: cabin-level daily price history across 9 lines, alerts, and — uniquely — the same sailing priced across US, UK, German, and Italian booking markets.

At a glance

Cruiseplum — best for power-user search

Cruiseplum is a cruise search engine with unusually good filtering: price-per-day sorting, cabin-category comparison, and a dedicated solo-traveler section. Reddit’s cruise communities recommend it often, and it earns that. Its limits are on the tracking side: the watchlist caps at 20 cruises with 5 active alerts, and it provides no deal scoring — you judge fair pricing yourself, as AllAboardDeals’ side-by-side test notes.

Cruise Radar — best while browsing booking sites

Cruise Radar layers deal scores and price context directly onto cruise-line booking pages as a browser extension. That in-context view is genuinely useful while shopping. Coverage is its constraint: roughly 8 cruise lines, with Holland America, Cunard, and Viking requiring other tools.

CruiseWatch — broad, but verify prices

CruiseWatch offers deal discovery and alerts across many lines. The recurring complaint in user reviews is accuracy: tracked prices that don’t match checkout (a documented case showed $638 quoted vs $808 at checkout) and mismatched itineraries. It holds a 3.2-star Trustpilot rating with roughly half one-star reviews. Useful for lines other tools miss — but verify every price on the booking site.

track.cruises — best for actually tracking prices

track.cruises records fares daily for Princess, Norwegian, Royal Caribbean, Celebrity, Costa, Carnival, Holland America, MSC, and Disney — per cabin type, so you see whether the Balcony or only the Interior dropped. Its distinctive feature is multi-market pricing: the same sailing is tracked in US, UK, German, and Italian booking markets, and the identical cabin regularly costs hundreds less in one of them. Price history depth varies by line (Costa has the longest record; recently added lines have shorter histories). The free plan tracks 2 cruises with digest alerts; Navigator ($8.99/mo) adds instant alerts and 1-year history.

FAQ

What is the best free cruise price tracker?

For search, Cruiseplum. For tracking specific sailings with alerts, track.cruises’ free plan (2 cruises, digest alerts). Many cruisers use both: search with one, track with the other.

Can a price tracker help after I’ve booked?

Yes — that’s where trackers pay for themselves. Before final payment, most major lines reprice or credit the difference on request. An alert on your booked sailing tells you when to call.

Why do tracked prices sometimes differ from checkout?

Some trackers show base fares without taxes and fees, or cache stale prices. Always confirm the final checkout price; treat any tracker’s number as a signal, not a quote.
