LOL I've been known to take as many as 1,000 pictures in a single day! (OK, so it was my bro's wedding day, but still) I never have a camera more than arm's length away). I plan to have extra SD cards, extra batteries.
I'm debating on video though, our video camera is large and clunky - I'm thinking I'll just stick to the little videos my canon powershot can take and just pick up some extra SD cards so I can take plenty of video.
