Health and Safety Protocols

THE COSTA SAFETY PROTOCOL, FOR YOU
To make you experience an unforgettable holiday in complete serenity, our health and safety team and a group of independent scientific experts have developed the Costa Safety Protocol. Furthermore, we are the first cruise company to have obtained the Biosafety Trust Certification from Rina and we carefully follow the safety instructions of the Cruise Lines International Association (CLIA).

1. EXTRA ATTENTION FOR EVERY SINGLE PASSENGER
CHECK-IN ONLINE
Check-in is carried out completely online and opens 72 hours before your departure. To receive your cruise ticket, you must fill in a self-certification questionnaire regarding your health status.
STAGGERED BOARDING TIMES
The boarding times are staggered to facilitate compliance with the correct social distancing rules and to ensure safe boarding. This is why punctuality is so important.
CONTROL AT THE TERMINAL
A quick health screening awaits you at the boarding terminal, which includes body temperature control and a Covid diagnostic test (swab), provided for all the guests*.

2. A SMART VACATION
MYCOSTA
The best way to ensure your on board safety is to check-in in advance. Visit www.mycosta.com before leaving, save time so you won’t have to check-in at the desks!
QR CODES
Your smartphone is a fundamental travel companion! Thanks to the QR codes you can now enjoy a wonderful vacation with complete digital security and it also means less paper to throw away!
ONBOARD MONITORS
There are other ways you can stay informed about what’s new on board: You’ll find digital screens and interactive monitors in public areas, a dedicated Info TV channel in the cabin and the new Call Me service, plus a convenient personalized assistance via the cabin phone.

3. MORE SPACE FOR YOU
REDUCED OCCUPANCY
The number of passengers onboard has been reduced to make social distancing easier and guarantee a safe and pleasant cruise.
REDESIGNED ENVIRONMENTS
The common areas and relaxation rooms have been remodeled so that they fully meet the safety standards you deserve: this means they are accessible to only a limited number of people at a time.
SAFETY SIGNS
There are signs in all high-traffic areas of the ship and the on-board staff will help you to get around easily and to maintain the correct safety distances.

4. ENJOY THE WHOLE SHIP IN SAFETY
PROTECTIVE MASKS
Just as on land, when in public areas while on board, protective masks must be worn By doing this, you protect your own health and that of your fellow travelers!
HAND SANITIZER
To help you keep your hands clean and sanitized at all times, in all the main areas of the ship you will find numerous sanitizing gel dispensers.
CREW DEVICES
The crew too have the necessary protective equipment to be able to do their job to the highest health standards.

5. BREAKFAST IS SERVED
SPACED OUT TABLES
Our restaurants are set up to welcome you in the best way while respecting social distancing. To ensure the safety of all our guests, we ask you to only sit at the table with the travel companion(s) included in your booking.
EXTENDED MEAL TIMES
Also, to order breakfast and lunch you can access the main restaurants entirely at your leisure, whenever you want, with a longer time slot than usual.
SMARTPHONE MENU
Scan the QR code that you will find at the tables, in the restaurants and bars, to check the daily food and drink menus directly on your smartphone. If you decide to order at the counter, follow the safety signs.

A WHOLE NEW ENTERTAINMENT
Enjoy the new forms of entertainment we have designed, with shows repeated several times during the week, and allow everyone to have fun at the same time, while still respecting social distancing rules.
SAFE FITNESS AND WELLNESS
Keep fit at the gym, have fun at the casino or relax with our spa wellness treatments or at the pool, in compliance with any signage and occupancy limits indicated.

7. EXCLUSIVE TOURS
COSTA SAFE EXCURSIONS
To protect your health and the one of the rest of the guests and crew, the descent to land will only be possible by purchasing one of our safe excursions.
LIMITED GROUPS
Costa excursions are totally safe: we have set out new procedures to ensure social distancing, thanks to limited group size and the use of disposable headphones to make for a better experience.
SAFETY ON BUSES
Our buses are sanitized after every use. Social distancing is guaranteed by reducing occupancy. In addition, our tour guides always wear protective masks.

8. PURE AIR AND SANITIZED ENVIRONMENTS
SANITIZIED PUBLIC AREAS
The public areas are sanitized several times a day with new disinfection methods including virus-killing nebulizers.
YOUR CABIN DISINFECTED
Your cabin is also subject to a virus-killing disinfection carried out by qualified personnel and is cleaned and sanitized on a daily basis.
NEW FILTERS FOR QUALITY AIR
On board ship, the air you breathe is of high quality thanks to the new high efficiency filters. Our on-board ventilation systems offer optimal filtering of fresh air from outside, minimizing the circulation of internal air.

The variety in their menu is limited. Have been on few cruises with Carnival and their selection of food is much better. Had a problem with the WiFi service on board the ship. Paid 32 Euros for a connection, but was unable to use the service. It appeared that most of my data allowance was used up when I switched on my laptop. I was told that the problem was probably due to my system set to automatically update itself.
