The mat simply is decorated with "Star Wars Weekend 2015" on the bottom (I ordered it from Etsy). I will definitely let you know how it goes. I figured worst case scenario I could "cut out" the autographs from the card (assuming we at least get that) and attach them to the mat, but I'm sure that would look really cheesy and would just tick me of every time I looked at it! Lol!! I'm hoping since we have a specialized item I can convince someone to help us out, but we'll see. We still probably would have done the breakfast even knowing they didn't sign, but I may have rethought the mat, as we don't plan to meet a ton of characters, and it will look stupid only half-filled
