Gift for my fiance on our big day?...

I'm hoping all of you out there can give me some advice. I still have QUITE awhile before my wedding, but I'm trying to think through every little detail. One thing that I can't quite think of was what to get my fiance to give to him on our wedding day. I was thinking of making a sort of scrapbook of everything leading up to the wedding, but he wouldn't really have time to look at it before the wedding. He proposed to me on a beach at my favorite campground, and our first vacation together was to Disneyland. I keep thinking that I'll get him something to do with one of these places, but I really can't decide what to do! There are probably lots of good ideas that I haven't even thought of. If anyone can give me some advice, that would be awesome!!
