Family holidays and kids’ clubs on board Costa Diadema
Costa Diadema is perfect for family holidays. Most cabins comfortably accommodate 3–4 people, and there are also connecting cabin options. The minimum age for cruising is 6 months. Spacious decks and convenient elevators ensure comfortable movement with a stroller. Parents can request a baby cot, high chair, baby bathtub, and bottle warmer. Diapers and ready-made baby food are not sold on board, but simple children’s meals can be prepared in the restaurant upon request, and baby food can be heated in the cabin.
For children aged 3 to 17, Squok Club and TeenZone offer games, creative workshops, and sports activities. Groups are divided by age: Mini (3–6 years), Maxi (7–11 years), Teen Junior (12–14 years), and Teen (15–17 years). There are playgrounds on board with castles, pirate ships, and pools. Programs are held in several languages, helping children make friends from around the world. On the first day of the cruise, you need to register your child in the club. For parents’ convenience, there is a “Parents on excursions — kids in the club” service.
Visiting the kids’ and teens’ clubs is included in the cruise price, and the flexible schedule allows parents to enjoy their vacation and excursions while children are engaged in exciting activities on board.
Where to eat deliciously? A question that will no longer bother you on the cruise!
On the Costa Diadema cruise ship, meals are organized under the All Inclusive system so you can enjoy your vacation and the sea views without any worries.

Enjoy every moment of your journey!
On board the Costa Diadema, it is recommended to have three types of clothing in your wardrobe: casual and sportswear for walks and activities, comfortable and weather-appropriate clothing for excursions, and more elegant outfits for evenings in smart casual and formal styles.
On official event days, cocktail dresses for women and suits with ties for men are welcomed. Evening shows, restaurants, bars, and clubs create an atmosphere of style and celebration where a more dressed-up style is appropriate. Beachwear, including shorts, flip-flops, and sneakers, is perfect for daytime relaxation on the deck or during excursions.
This approach helps create a pleasant and festive holiday atmosphere that brings joyful impressions to every guest!
