Long or Short box on WGI Short Course

My son would like to race the July Sprints this coming weekend at Watkins Glen. For some reason I was under the impression that this race was going to be on the long course. Come to find out, it will be on the Short course. I have heard/read that the long course is a short box and the short course is a long box setup. Can anyone who races WGI regularly confirm this is correct. He would like to be competitive, not lose the draft and if that is not possible with a short box, we will most likely pass on this weekend.

Thanks,
Rob
