When I was there at Xmas, it went like this. All guests walked up the same path, the main one beside the B and B show sign and such. At the apex of the hill when you reach the back of the seating area, there was CM's waving everyone to move down to the left to fill the next section for seating. To the right (far right is the dining reserved area) there were two CM's manning a rope that stretched to not allow folks past. On the rope hung signs that said reserved dining package only. Those with the package needed to see the CM to get let past. The "regular" guests are mostly all seated 45-1 hour before the show just to get in. The dining guests don't show up until 15-10 minutes before the show. Thus, it was not really a big mix-up.
