The 2003 series was in Wigan, Huddersfield and Hull. I went to the Wigan one where Moz got sent off after 12 seconds.
There was some iconic series before that at Wembley, Old Trafford and Elland Road, but if you try and use grounds like that (or Etihad, Anfield, St James' Park etc) then all you will see are thousands of empty seats.
I'd make the London one a bigger one - Wembley, Spurs, Arsenal or West Ham - and then use Wigan and either Leeds (Headingley, not Elland Road) or Hull.
