No you won't notice a difference.
While alpha acids and precious volitiles fade with age and air exposure. You won't register any difference with the limited time you're talking about. I would wrap them in foil or use a zip lock, to prevent contamination that may not get sterilized (whirlpool additions), and at least refrigerate.
