I do mostly photography, but I do carry a video camera (and could shoot video on my phone too). I like video for shows some (I'd like to get the Candlelight Processional on video when we go this year), but mostly for people--character interactions, my father being goofy, and sometimes I do little video interviews while we're waiting for fireworks (what did you like best about today? what are you hoping to do tomorrow? that kind of thing...).
Last trip, when we got home I made a DVD of still photos + video clips with Disney music in the background. We always do a scrapbook too, but I think I would make the DVD again. It was great for showing pix to the family and for reliving the trip.
