The Crew Center, a website run by former cruise ship crew members, says that Norwegian Cruise Line will cut back on the cleaning of its staterooms.

Guests booked in studio, inside, oceanview, balcony and club balcony rooms will no longer receive twice- daily stateroom service. The rooms will get once- daily service.

All other suites and Haven categories will not be affected by the change.

NCL said in a statement that it is committed to providing high quality service and having a positive impact on the environment.

In order to reduce our carbon footprint and apply sustainable practices across all aspects of the business, we have made modifications across the fleet.

The new policy will be rolled out fleetwide by the end of March.

The reduction in service will conserve water, energy and the use of chemicals and is in line with standard practices in the cruise and hotel industries.

Crew Center says the change will change titles and pay for stateroom stewards. The title "stateroom steward" and "junior stateroom steward" will no longer be needed. stateroom stewards will see a salary decrease on their next contract if they were previously in the position of junior steward.

NCL increased gratuities for guests booked in suites. Haven and suite guests will be charged 25 cents per day, up from 20 cents. All other guests will be charged $20 per day, up from $18 for club balcony suite guests.

If guests prepayment their service charges before their sail date, they can lock in the previous rates. It is possible to add pre-paid charges up to 24 hours prior to sailing.

An NCL statement was added to this report.
