Fanciful and grossly overthought. It also doesn't work that way.
In the event of an actual abandon ship, you won't be taking anything with you but the clothes on your back — everything is left behind. The orders from the people managing the emergency take precedence over your desires to take something to seemingly afford a better chance of survival, or to provide comfort. You will certainly look the part
with lifejackets on!
Costa Concordia was the result of careless, cavalier navigation, a showy display of affection toward the shoreline that went pear-shaped through inattention of where the ship was drifting — straight for a reef.
I toured Canada with APT for a month in 2012. We attended emergency drills 2 weeks before the trip. As the tour went on (and on and on), emergency briefings were regular occurrences for shoreline excursions (e.g. Park Glacier).
Similar to this —

( I was the youngest person on that tour! Everybody else was 80-90 and could hardly see for cataracts!
)
Once the cruise gets underway (you're going with Cunard!?
Pack a noyce suit or two!) there will be cruise briefings before the actual departure, not necessarily on the ship, but in their, or associates' offices, like APT do.
In a nutshell, when things get topsy-turvy, you are best just leaving everything in the hands of the ship; grabbing things to take only complicates and slows evacuation (apart from going against prevailing regulations) and elevates an already stressful situation for the crew managing the emergency.
Cruise ships are veritable petri dishes for bacteria. I had a gut ache from something mixed with seafood. As recent history demonstrates, COVID is and will remain a bigger threat to personal health than a ship toppling over. Once that gets going in a ship, you're stuffed. True dinks.
