Life onboard
What it actually feels like to sail Costa Smeralda— entertainment, food, and the crowd you'll find onboard.
Entertainment
The Smeralda has sleek, modern entertainment spaces—a contemporary theater with nightly stage productions, a lively nightclub, and multiple bars and lounges scattered across the ship. You'll find everything from trivia contests and poolside activities during the day to comedy shows and dancing late into the night; the overall energy is vibrant without feeling forced.
Food & dining
Costa emphasizes Italian cuisine, so expect well-executed pasta and Mediterranean flavors in the main dining room and buffet, alongside international favorites. There are several specialty restaurants onboard (usually à la carte) for upgrades, plus casual pizzerias and cafés for quick meals; the buffet is modern and varied, reflecting current cruise-line standards.
Atmosphere
This ship appeals to modern, active cruisers—multigenerational families, couples, and solo travelers seeking contemporary style with approachable luxury rather than ultra-premium exclusivity. The design is sleek and Italian, with vibrant public spaces and smooth traffic flow; it strikes a balance between party-forward and relaxed, drawing people who want activities and structure without feeling like a floating resort town.
The ship & service
A closer look at Costa as a line, Costa Smeralda as a ship, and the service and deck quality to expect onboard.
- The line
- Costa Cruises is a mainstream European line, part of the Carnival Corporation family, marketed primarily to Italian and continental European travelers. It's known for an upbeat, social atmosphere with a distinctly Italian flair - Mediterranean cuisine, espresso bars, and lively public spaces - at accessible mass-market price points rather than premium fares.
- The ship
- Costa Smeralda is the lead ship of the Smeralda Class, in service since 2019, making it one of the newer and largest vessels in the Costa fleet. At roughly 6,700 guests it feels unmistakably big, with sleek contemporary Italian design, a multi-deck atrium as a social anchor, and one of the first LNG-powered hulls in mainstream cruising.
- Service
- With about 6,700 guests to 1,700 crew (~3.9:1), service runs at typical mainstream mega-ship volume rather than personalized luxury - efficient and friendly at the bars, buffet, and main dining room, but you won't be remembered by name. Expect attentive service in specialty venues where ratios improve, and busier touchpoints during peak embarkation and dinner.
- Decks & spaces
- As a 2019-built mega-ship, public spaces feel current: a modern pool deck with multiple pools and hot tubs, expansive sun decks, and contemporary lounges and bars finished in glossy Italian-design materials. The atrium is a tall, theatrical centerpiece, and outer-deck flow accommodates the high passenger count; upkeep should be solid given the ship's relatively young age.
How the score was built
We compare the reviewers of this ship against every other ship those same people sailed and rated. Each review is scored relative to the reviewer's own baseline — four stars from someone who hands out fives means something very different from four stars from someone who rarely goes above three. Every reviewer then counts the same, so the result is a calibrated consensus rather than a star average.
- Global percentile
- Where Costa Smeralda lands against every ship we rank.
- In-cohort percentile
- The same comparison narrowed to its cohort — the other ships in the same fleet, so a line's budget hull is judged against its own sisters rather than against a luxury expedition ship. Ranked against Costa (17 ships).
- AI-adjusted percentile
- The same reviewer-normalized score, corrected for how much confidence the sample supports: thin samples are pulled toward the corpus average. Each ship keeps the share n / (n + 53) of its measured distance from the average, where n is its calibrated-reviewer count, and the result is ranked on the same scale as the global percentile.53 is the median sample size across everything we rank. Here n is 6.
