Patty asked "Is there some sort of shortcut for those of us who don't need another 10 hour a week hobbby?" and that is a valid concern. She is absolutely right that getting into scrapbooking can be quite time- and money-consuming. But there are other ideas that you might try as well.
One quick idea is to get a photo album that has sleeves for pictures. Just slip in a group of photos and intersperse them with a few mementoes (such as ticket stubs, flyers, postcards, etc.) and/or journaling, either hand written or printed on your computer. The journaling doesn't have to be elaborate, but jotting down a few details will provide reminders so everyone can enjoy the event again at a later date.
That gives you a relatively fast & easy way to preserve your memories without spending a great deal of time or effort. Please let me know if that seems feasible for you.
