We've just returned from our cruise on the NCL "Epic". We stayed in the "Haven" Courtyard penthouse suite. Our question is, what's the general rule for tipping your personal Butler and Concierge over the course of the cruise? We couldn't seem to get any type of answer on this question. The $24 a day that is automatically taken out of your shipboard account for general tips does not include the Butler or concierge. Although we have always left extra $ for exceptional service, we think it would've been a very good idea from a travel agent / cruiseship to point out the fact that this is something completely separate and to keep that in mind while budgeting for your vacation.
