Your tickets should be for specific seats. Silver 4 or 3 are probably the better stands, then they’re divided into sectors, silver 3 better sectors are a,b,c or d.
Only negative is that you can’t move around into other stands, but you can, on the Friday and Saturday, pretty much sit in any seat as these days aren’t heavily populated.
Good luck and enjoy it. If you haven’t been before, I’ve posted a handy guide. Take a look at it.
