I agree with Heather about the plastic expanding envelope. They are somewhat rigid, so all of those park maps, menus, napkins, etc. that you bring home are in excellent condition when you get ready to scrap.
If you use a digital camera, I would learn how to hook up the camera to a television so you can review your pictures on the TV in your resort. Then, make sure you pack the patch cord to hookup (voice of experience here). That way, if there is a really special picture that you want, you can make sure it's not fuzzy, off center, etc. before you go home. Also, it's a great way to see which pictures can be deleted, freeing up disk space for the next day's pictures.
