This will be the first time sailing with shareholder OBC. I seem to recall reading in the fine print that it cannot be used for "gratuities". In your experience, is this true? I'm used to my OBC just going against my ship account in general. Will they actually tease out the 18% auto tip on drinks, daily crew appreciation etc.? Just want to know what to expect. For clarity, we are NOT sailing with a princess plus package.
