congrads to getting married. If your wife is into photography as u... by all means bring all the gears. if not... my advice is that you just bring a P&S. Give her all your attention and take a lot of pictures together with her. cause it does not matter if it turns out good or not.
Otherwise the only thing getting any action is your dslr, and u will be sleeping in the hotel lobby. dun screw up the honeymoon.... she will remind you throughout your married life.
