Well, no clue when in December you are sailing or what ship you are on so I suggest you look for the Roll Call for your sailing and ask there.
Click on the "find your roll call link" at the top of the page.
Enjoy your cruise.
Some people will tell you, yes they get them. Some people will tell you, no they don't get them. Some people will tell you they get part of them. Some cruise workers will tell you stories to get more money.
Take your pick. 🙂
At the top of each thread is a "Follow" button. Click on that and you will see options for notifications. I believe that is what you are looking for. 🙂
Tom, recommend you ask/research on the Cruise/Travel insurance forum. Lots of good info to peruse. Link:
