Yup, they sell the 12x12's as well as stickers and filler 12x12 pages. I bought mine on our July '04 cruise. Sorry can't remember the $$, but they were reasonable. I doubt you'd pay any more or less at Michaels, Hobby Lobby or other scrapbooking store.
I bought the album. It come with 12x12 paper in white and primary colours, 15 page protectors and a nice pocket page for loose papers/Navigators etc. I also bought the "2004
DCL Scrapbook Kit" that had:
1 sticker sheet,
6 designed paper sheets,
4 solid colour sheets (primary),
3 sheets of adhesive backed shapes(die cuts)
4 paper frames, and
1 sheet of border stickers.
I also bought extra Disney stickers.
Hold on, found some $$; sticker sheets; $3, alphabet stickers $5, scrapkit $15, If I remember the scrapbook was either $20 or $25.
Something to think about with the scrapbook. Buy the book or paper pages early. Then, when you go to get character photos, take a scrap page and have the character sign the page. We also had our servers sign a page. Have tablemates or friends you meet or CM you enjoyed sign pages too! Then when you add thier pictures you have their autograph and a nice comment or two from them too!
We had no shortage of scrapbook stuff on board and our cruise was FULL!! I bought mine on Thursday night (I think). Still plenty on the shelves.
HTH!!
