There will be no automatic charge to the on-board account for passengers who travel on Cunard. It is up to the passengers to tip cabin and restaurant stewards. It is not necessary to tip, but Cunard gratuities are appreciated. For example, Britannia Staterooms, gratuities are $11.50 per person, per night, and on Grill Suites, they are $13.50 per person, per night. Regardless of age, the charge is the same for adults and children.
