Anyone already booked can prepay at the old rates; guests booking by Aug. 1 can also prepay at the old rates.
It is the second time this year that Norwegian has raised gratuities for staff members. On March 1, the rate went up from the previous suggestion of $12.
When not pre-paid, gratuities in the suggested amounts are automatically added at the end of a cruise to a customer’s onboard account. They can be adjusted upwards or downwards by visiting guest services.
Other cruise lines are also raising gratuities, including Royal Caribbean International, which raised its rate on June 1 to $12.95 for most cabins and $15.95 for suites.
