i have looked into this a bit. There are a few specialty restaurants that charge a cover-charge to eat there. If you go to these restaurants, tip as you would any normal restaurant back home. As for automatic tipping, its usually figured at 15% - it is added automatically to your shipboard account --it usually covers - room steward, waiter, assistant waiter, head waiter and maitre-d. You can adjust the amount or remove it totally and tip the old-fashioned cruise ship way with envelopes at the end of the cruise. Visit NCL's web site they have a list and description of all the restaurants including the ones that charge extra.
