I love using multiple pics in my LOs, as well as interactive elements etc to fit even MORE in! (Feel free to check out my gallery - )
But yeah you can't scrap 'em all. You'd drive yourself crazy trying to (though I do try to scrap MANY to MOST). I keep regular photo albums in addition to my scrapbooks.
Also, we have a digi cam so I try to only print the ones that I really like &/or think I'll scrap, so we have less prints to deal w/ to begin w/.
