Croke Park here in Dublin is a capacity ground of 92,400.
Hill 16 at one end of the ground was left terraced under the redevelopment a number of years back.
It holds approximately 10,000 but it is where I mostly go on match days.

It is extremely safe and well marshalled with plenty of facilities. Cracking atmosphere and colour and frequency mixed supporters mingle. The tickets are cheaper then the stands....but still a fantastic atmosphere...
Terraces work....as long as not made for sardines...
