With 13 categories of stateroom, you'll be sure to find the perfect cabin to suit your needs. Interior staterooms measure 150 square feet and come with two twin beds which can be pushed together to form a queen-size bed, a private bathroom, storage space including a safe, and a flatscreen TV. Many staterooms also have a sofa bed or a Pullman bed and can sleep up to four. The popular Samsara spa staterooms and suites come with exclusive spa access, upgraded bath products, and healthy snacks in the minibar, and suites come with a private verandah, a sitting area, and a whirlpool. But choose your stateroom carefully – rooms located near the bars and clubs can be noisy at night.
Dining & Gastronomy
The Costa Diadema offers seven different dining venues, four of which are included in the cost of your cruise. The two main dining rooms, Adularia and Fiorentino, are assigned-seating venues serving authentic Italian dishes in an elegant setting. Corona Blu serves as the ship's buffet during the day and turns into an open-seating dinner venue at night. Spa-class passengers as well as health-conscious guests will appreciate the lighter, healthier fare in the Samsara Restaurant, and Club Diadema is an upscale Italian restaurant offering gourmet sit-down dinners. Piazza Pizza serves Italy's most famous export in the evenings, and for those getting tired of pizza and pasta, Tavola Teppanyaki provides a welcome change with its Japanese-style grill. Don't forget to stop by Gelateria Amarillo for dessert!
Entertainment and Activities
The Emerald Diadem is a nonstop flurry of activity. Spontaneous dance shows, acrobatic performances and musical performances pop up in nearly every public area of the ship throughout the day, and the theatrical productions and movie screenings are popular among passengers of all ages. Though the ship has designated clubs for small children and teens, the entire ship is family-friendly, meaning you'll find kids and teens in nearly every public area of the ship – even some of the dance clubs at night. To get away from it all, retreat to the calming oasis of the Asian-themed Samsara Spa, where you can enjoy a relaxing massage or a rejuvenating beauty treatment in a calming atmosphere.
Though the Costa Diadema has no formal dress code, passengers are asked not to wear shorts in the restaurants in the evening and no swimwear at the buffet. Though occasional Formal Nights and some themed dinners call for a formal dress code, these are not strictly enforced, so don't sweat it if you forget to pack your tux.
