Reviewer read

One of the lowest-rated ships we track. It falls behind on service.

Costa Diadema rates higher overall than 1% of the ships we track. The weak spot is service — and a small but very consistent signal says it is getting worse.

Why reviewers choose it

No category on this ship rates clearly above the fleet.

The one caution

5.9out of 10 for service

Higher than only 0% of ships. The typical ship scores 8.66.

Of the 11 reviewers who described service changing over time, 10 said it got worse.

Consistent, but only 11 people said it.

Everything else, in one line

Eight fall below the fleet: cabins, embarkation, public areas, dining, fitness, value, service and entertainment. They rate higher than 0% to 3% of ships.

Activities, Ship quality and Disembarkation fall below the fleet too, on 55, 57 and 38 ratings — too few to lean on.

Family has too few ratings on this ship to compare with the fleet, so it is shown without a comparison.

Who says it suited them

First-time cruisers (12 of 14).

No group described it as a poor fit.
