I'm an old bride but my thought on this was that I was on vacation for the happiest week of my life and in the end I wanted happy memories. For me, counting calories/fat/carbs whatever would have turned happy into unhappy. My fiance sure wasn't worrying about anything and I didn't want to be either. I didn't go crazy but I wasn't afraid to eat. In a few days time you won't gorge yourself to the point that your dress will not fit, unless it barely fit in the first place and that's a separate issue, you know? I say relax and enjoy yourself. It's a celebration
