Best and worst cabins on Diamond Princess

Most cabin advice is somebody's opinion. This is measurement. We read the published deck plans for Diamond Princess, worked out where each of the 1,351 cabins physically sits, and ranked them.

Diamond Princess is about 115,875 gross tons, carrying around 2,706 guests at double occupancy, in service since 2004. The cabins we can place on the plans run from deck 5 to deck 14. The deck plan legend colours them as 574 balcony, 377 interior, 214 suite, 186 ocean view.

On this measure the steadiest cabin aboard is P246 on deck 5 (Balcony), and the one that should move most is L311 on deck 14 (Balcony). Every other cabin on Diamond Princess falls between the two.

How this is worked out, and what it does not cover

A ship pivots about a point amidships and low down. The further a cabin sits from that point, the more it moves in a swell. So the ranking below is distance from amidships, weighted with height above the waterline. It is a position measurement, not a review.

What we are not claiming. We have not mapped the bars, clubs and galleys on this ship, so nothing here is a noise rating. A steady cabin under a nightclub is still a cabin under a nightclub. We also could not establish which end of this ship's plans is the bow, so we describe cabins as amidships or near an end rather than forward or aft.

The steadiest cabins

Closest to the ship's pivot point. If you are prone to seasickness, start here.

The cabins that move most

High up and close to an end. Fine for most people, worth avoiding if you are not.

The largest cabins

By floor area on the plan, against the median cabin on this ship. Suites will dominate, which is the point: this is where the space is.
