New to cruising?
Start here
Six things to understand, in order. Work through them and any cruise offer becomes readable — what it is, where it goes, how it is structured, who runs it and what the price actually covers.
Step 1 of 6
Choose the type of cruise
Ocean, river and expedition cruising are three different products that happen to share the word cruise. The type decides the size of the vessel, whether there are sea days, whether you arrive in a city centre or at a landing site, and how much of the day is set by conditions rather than a timetable.
Ocean
Large ships, a sea and its coastlines, port days and sea days.
- Sea days
- yes
- Arrival
- port, sometimes by tender
- Vessel
- large
River
One navigable corridor, small vessels, city-centre moorings, no sea days.
- Sea days
- none
- Arrival
- city-centre mooring
- Vessel
- small
Expedition
Small vessels, few or no ports, landings by boat, condition-dependent routes.
- Sea days
- possible
- Arrival
- landing by boat
- Vessel
- small
If the difference between the three is still unclear, cruise regions explained sets out how the world is divided up.
Step 2 of 6
Understand the geography
Once the type is settled, the next question is where. Each type has its own geography, and it determines the season, the distances between stops and what a day actually looks like.

Step 3 of 6
Understand the itinerary
An itinerary is a plan, not a promise. What matters is its shape: where it starts and ends, how many stops there are relative to days at sea, how long each stop lasts, and how long the whole voyage is. Two sailings to the same region can be structured very differently.
- 01
Departure point
Round-trip from one place, or one-way between two.
- 02
Stops or landings
How many, how long, and whether the ship docks or tenders.
- 03
Sea and scenic days
Time that belongs to the ship, not to a place.
- 04
Duration
And how much of it is spent getting to and from the region.
Step 4 of 6
Understand the operator and the ship
The same route feels different on a different vessel. Ship size decides which places can be entered directly and how many facilities exist; the operator sets the onboard model.
Cruise line
The operating model behind the sailing: what is included, how formal it is, who the ship is built for.
Cruise line overviewShip size and type
Port access, stability, facilities and how many people share them.
Ships explainedCabin
The part of the ship that is yours, and where it sits on board.

Step 5 of 6
Understand what you are paying for
A cruise fare is layered, and the layers differ between operators. Knowing which categories usually sit inside the fare and which sit outside it is what makes two quoted prices comparable at all. This site describes the structure; it never publishes prices.
Inside the fare
- Accommodation
- Most meals
- Onboard entertainment
Usually added
- Taxes and port charges
- Service charges
- Drinks
- Excursions
- Connectivity
Outside the cruise
- Flights
- Transfers
- Pre-cruise hotels
- Insurance
Step 6 of 6
Then look at specific sailings
Only at this point does a specific ship, date and price become readable. That stage belongs to the cruise line and your travel provider, who hold the availability, the terms and the documentation. SnapVoyages deliberately stops here — there is nothing to book on this site.
- Compare like with like: same region, similar length, similar inclusions.
- Read the fare structure before the headline number.
- Check documentation, accessibility and insurance against your own circumstances.
