I enjoy the creative process of scrapbooking, as opposed to just putting all my photos in an album. I like the process of finding embellishments to go along with the photos (decorative photo mats, maybe some stickers, maybe a page border or title, maybe a picture of a Disney character that I've created from pieces of cardstock based on a pattern in a coloring book, etc) to add a little extra "zing" to my pages.
The other major reason I scrapbook is the journaling. This is simply writing down your memories about a particular event. I may write about how the kids seemed to feel about a particular ride or meal or character or something. I may write about how I felt, or just general information about WDW.
I also save memorabilia from our trip: our tickets, the park maps, any other little pieces of stuff.
I use a variety of scrapping styles, too. Some pages are very simple, so the complete and total focus is on the photos alone. Other times I use more elaborate page embellishments, but never enough so the photos are not the main focus. I like my embellishments to accent, not overpower, my photos.
I teach scrapbooking, so if you would like to email me privately, I can teach you more (for free, absolutely no charge) about the basics of scrapbooking in private email. Anyone who wants to know more is welcome to email me, too.
