Just once, and we were quite surprised to have the liquor we were carrying onboard from a port completely ignored by the crew. I don't remember whether we were on a Princess or Oceania cruise. In either case, and this might be a bit of bad news, we had purchased a drinks package as is our custom. From the perspective of the cruise line, I would strongly encourage passengers who have purchased a drinks package to buy liquor in ports, if only because it means they won't be drinking the boat's booze, but their own. Just financial sense.
