Mine is finished. I saved all of the navigators and the map of the ship they give you at checkin, as well as some receipts, my shutters card and I purchased several postcards along the way.
The album is in chronological order, starting with arrival at the port and ending with us getting back in the car at the end of the trip.
I included our ressie confirmation information, sent postcards home from the various ports so I could include them in the book, took pix with our room steward, all the towel animals and our servers. I included the stubs from the gratuities so I would remember their names. Gave any formal portraits and character photos their own page, but double matted the images to make them stand out. Found a cute bumber sticker at the Turtle Farm that I used as a title page for that section.
Don't forget to journal!
