Thank you for clarifying what the arrows are for Gilly!! Since this will be my first trip to York, I will need some guidance! So the arrows are just what I need!!
Just to expand a little .
They are more necessary in the member halls(Red/White/Blue/Silver), you will see them there most likely everywhere (unless one got peeled up off the floor).
You won't see them in Purple, it is spread out enough in there now (unless there was a massive increase in tables this meet! ) that they aren't needed.
You will see them on Orange, but primarily only in the "front half" of the room where tables are set up in the back-to-back format from aisle to aisle. The "back half", small side room(s), and first aisle or 2 in from the side walls in the "front half" don't have them where it is set up in booth format, as the aisles are much wider there and arrows are not needed as much. I think there occasionally has been a situation in the front of Orange where 2 adjacent aisles may have had the same direction arrow. If you bump into that, it's easiest to just back track one aisle to turn around and then skip over the most recent aisle you just looked at to pick up the new one.
All common sense, but if it was common, there would be no announcements.
