Last year I was an Ambassador and was assigned to the area you will be in.
The question came up then. We were told that cutting through was OK.
When I stood to the side and watched turn ins ( if you have not seen that , it is quite a sight especially in the open), multiple doors were open, and teams approached from all directions.
Judging area is totally screened off, so no matter which way you came, there were no sight lines back and forth to the judges.
Good luck.
Will be an Ambassador again this year - hope to see you and lots of other Brethren there.
