I realize this is an exercise in futility, but that ticket contract has always said they may hold it. Specific wording or numbers may have changed over the years, but it's never said it's ok to do it. BUT, in the 14 years I've been reading the Oceania board you are the first to say it was confiscated. Meanwhile many of Oceania regulars, myself included, has brought on hard liquor on pretty much every cruise they've been on with Oceania. Not saying it didn't happen to you, but it's never been the norm. Maybe you were observed pouring outside of your stateroom, or perhaps your file mentioned excessive drinking. Who knows.
