As a frequent Princess cruiser, we are accustomed to the drill shortly after leaving port and their usual recording "we have technology that precludes the need for a rollcall at the muster station". For our recent cruise out of Venice to Barcelona (a repeat journey), the drill came before port and they scanned each card at the muster station. For those folks who did not show up, they got a letter requiring them to show up at 7am the next morning at the muster station for life jacket training. We heard a few who were ticked. Good for Princess (also owned by Costa). I assume all lines are taking it quite serious as you never know.
