Everything You Need to Know About Tipping on a Cruise Ship | ThePointsGuy

Some cruise lines call them service charges. Others call them gratuity charges.
Either way, the daily service fees that some cruise lines tack onto passenger bills can be a shock to first-time cruisers.
At some lines, these charges run as high as $25.50 per day. And, unlike the typical service fee or resort fee found at a land resort, they are not per room. They are per person.
At many big lines such as Royal Caribbean and Norwegian Cruise Line, it’s not uncommon for a family of four staying in a single cabin to see around $60 a day in service fees added to their bills. On a typical seven-night cruise, that’s more than $400 in fees!
