01

Where the prices come from

We read cruise-line published US/USD fares and re-check them daily. A line appears only after we have real tracked data for it.

Every public number is attached to a line, sailing code, departure date, pricing basis, and timestamp where the data model has it.

02

How cost per night works

Cost per night is the discounted per-person fare divided by itinerary length. It keeps a 7-night sailing and an 18-night sailing comparable.

Each line quotes differently, so we label the basis instead of silently mixing per-guest, per-sailor, and cabin-derived prices.

03

How value is scored

A sailing detail page compares the current fare with that sailing's own recorded history.

Ranked lists compare a fare with similar live inventory. Thin cohorts are treated carefully; a supplier discount can support context, but it does not create urgency by itself.

04

What we do not claim yet

We do not yet net out inclusions such as drinks, gratuities, excursions, or wifi as dollar values.

A per-night number is a pricing signal, not a complete onboard-value model. The line pages keep the basis visible so the comparison stays honest.
