It all depends on when you BG is. If you are real early you should be fine as long as they start with the BG right away. However, you just cannot tell right now. Typically, you should be okay at 1230 especially if you get a higher BG. It all depends on how quick you are with the app. We did a late diner at 820 and were fine. If sci fy is packed and running late you could have issues if you fall in the BG time as its typically about 1 hour from check in at ROR to finish, thats assuming no breakdowns while you are in line.
