a4e - I had the same problem with the map. This might help a bit [
Link] e.g. it shows P5, P6 and P7 are next to each other not above or below each other, but from our ticketing map you still can't see where the pitch is.
Also, after eventually managing to get one adult and one senior ticket next to each other our site would not let me buy both, even though my friend is in my friends and family list. He is in priority group 2, so he'll have to try to get the seat next to me after 4pm.
