I wouldn't take anything that you would mind losing. I would bring another stuffed animal, or bring one that isn't dear. While we don't like to think about anything bad happening, the reality is that it can. If it comes to manning lifeboats, you may not have time to go to your cabin to get Tigger. Remember that cruise ship that sank recently -- all of the passengers' possessions went down with it. Leave cherished items home where they are safer, and only bring jewelry that you wear most of the time.
