It’s unreserved so you can stand where you want.
However I would suggest if you want the best view, get to the ground a little earlier before it fills up and people get into position.
We got to the ground with very little time to spare last time and we were stood towards one end near the touchline and it does affect your view of other parts of the pitch.
We had to move at half time, but luckily we got a great view of McGoldrick’s double in the second half. So all in all it was a very enjoyable experience.
