Nope, I wouldn't take any scrapbook stuff with. I took my laptop so I could clean out my memory card, but that's about it. They come on your cabin, and move stuff around when you aren't there, so you can't leave anything out, AND there isn't anyplace to spread out in your cabin.
Take lots of money to buy cruise related scrappy stuff that they usually have onboard, and plan on room in the suitcase for all the navagators, and other paper stuff you will be saving, like special menus, excursion ticket stubs, pics. I had a little box in my suitcase so that stuff didn't get bent up when I was packing for home.
Have a great trip! Oh, and the best tip I ever got for cruising was to pack an over the door shoe holder for the bathroom! If you don't have one packed yet, get one, you won't be sorry. Got all the "stuff" in a place where I needed it, but not on the little counter.
