Cruiseplum Alternatives for Solo Cruisers: 5 Trackers Compared
Why solo cruisers need a different price tracker
Cruise price trackers solve a real problem: fares change daily, and most people never notice a drop. The catch for solo travelers is which price gets tracked.
Cruise fares are advertised "per person" based on two guests sharing a cabin. When you book alone, you pay the single supplement on top. On Norwegian Cruise Line, a solo traveler in an inside cabin typically paid approximately 1.6 times the per-person fare two guests paid for the same cabin, based on CabinSaver tracking as of September 2026 (subject to change).
So a tracker that alerts you to a "$499 per person" price drop can still mean a solo fare of approximately $800 at checkout. A good tracker for solo cruisers needs to answer one question: what will this sailing cost me, alone, per night?
Below are the five tools that come up most often when people search for Cruiseplum alternatives, compared on that question.

CabinSaver: built for solo cruisers
CabinSaver is the one tool in this comparison built around what a solo traveler actually pays. Three things set it apart.
Every price is your solo price
CabinSaver prices every sailing for a single guest, with the single supplement already included. General trackers are built around the two-guest "per person" fare, so the number they show is not the number you pay alone. CabinSaver also ranks deals by solo price per night, so a 4-night and a 12-night sailing are compared fairly.
Deals come to you
Most trackers start with a sailing you have already picked. CabinSaver starts with every upcoming sailing on 7 cruise lines and shows the cheapest solo fares first, so you can find a deal before you know where you want to go.
When you do know, narrow it down. Filters cover cruise line, ship, departure port, ending port, ports of call, destination, cabin type, trip length, travel dates and round-trip only.
No account, no waiting
Open the deal finder and start browsing. There is no sign-up. The cheapest sailings appear first while the full list loads in the background, and the deal finder works on your phone as well as your computer.
Also included:
- 7 cruise lines: Norwegian, Carnival, Celebrity, Cunard, MSC, Royal Caribbean and Virgin Voyages
- Couples and groups too: every sailing is also priced for 2, 3 and 4 guests
- Daily solo deals: current deals updated every day
- Deal alerts: pick your lines, home ports and a max price per night, and get notified when a solo fare matches
- Price charts: see how fares move over time for each cabin type, so you know whether a price is actually low
- Studio vs. inside comparison: NCL studios are built for solo travelers, but they are not always cheapest. As of September 2026, inside cabins were priced at or below the studio on about 21% of NCL sailings offering both, based on CabinSaver tracking (subject to change).
Where it falls short: CabinSaver covers 7 lines, not every cruise line. If you sail Princess, Holland America or a river line, you need a general tracker.
Cruiseplum
Cruiseplum is a cruise search site built by cruise enthusiasts. Its standout feature is a base-fare history chart broken out by cabin category, plus a price breakdown that shows fare, taxes, gratuities and total.
- Cost: free account
- Limits: 20 cruises on your watchlist and 5 active alerts
- Best for: travelers who want deep price history across many cruise lines
For solo travelers, Cruiseplum is not built around single-occupancy pricing. You will get more out of it when you already know the sailing you want and are tracking it for two guests.
Cruisewatch
Cruisewatch offers some of the most flexible alerts among general trackers. You can filter by line, ship, destination, departure port and length, then get alerts on price drops, price increases, sell-outs and newly available cabins. You can also set a target price.
- Cost: free account
- Limit for solo travelers: alert prices are based on the double-occupancy fare, excluding taxes and fees
That last point matters. A Cruisewatch alert tells you the two-guest fare dropped, not what you would pay alone.
Cruiseline.com fare tracker
Cruiseline.com is a simple option. Enter an itinerary and your email, and it emails you when the price changes and by how much. No account is needed.
- Cost: free, no sign-up
- Limits: you cannot set a target price or choose a cabin category
Good for watching one sailing you have already picked. Not useful for finding new deals.
Cruise Critic price tracker
Cruise Critic shows the last 90 days of prices for a sailing. It does not send alerts, so you have to check back yourself.
- Cost: free
- Best for: a quick check of whether today's price is high or low
Which tracker should you use?
Best for solo travelers: CabinSaver
In our view, CabinSaver is the best Cruiseplum alternative for solo cruisers. Of the tools compared here, it is the one that prices and ranks every sailing by what one guest pays, with no account needed to start.
Best for other situations
- You cruise as a couple or group: use CabinSaver with 2 to 4 guests selected.
- You want deep price history across many cruise lines: use Cruiseplum.
- You want the most alert types: use Cruisewatch.
- You already booked and want to catch a drop: use Cruiseline.com.
- You sail a line CabinSaver does not cover: pair Cruisewatch or Cruiseplum with the line's own solo pricing at checkout.
Whatever tool you use, always price your sailing for one guest before booking. The "per person" fare is not your fare. For more on why, read why solo cruises are so expensive and how to cruise for less as a solo traveler.
