I touched this topic in another thread and it has made me wonder where certain rounds should be played in the World Cup in 2013, here is my opinion:
Final - Old Trafford/Wembley
Semi's - Etihad/Old Trafford and Millenium
Quarters - Elland Road, KC, DW and Galpharm
Groups - Halliwell Jones, KC, DW, Galpharm, Headingley, Leigh, Langtree, Salford, The Stoop, The Shay, Keepmoat, Wrexham, Stobart
Other Options - Reebok, Emirates Stadium, Bristol
These would be my choices.

No HJ there pal

Reebok could be an option.

Will they just say which will be used or which will be used which games as well?

Stobart?

Somehow I think you are being a little optomistic.

Bristol seem to have invested an awful lot of effort into being a host ground.

I think the MS3 Craven Park will hold a game, possibly a group game with PNG with the link to Gene. I know others will disagree

I wouldn't disagree with that. It was a collaborative Hull bid as well, so if Hull get a game you'd expect Rovers to get a game as well.

These are the stadiums which have made a bid to host games.

Keepmoat Stadium, Doncaster, England
Millennium Stadium, Cardiff, Wales
Spotland Stadium, Rochdale, England
KC Stadium and Craven Park Hull, England
Halliwell Jones Stadium, Warrington, England
DW Stadium, Wigan, England
Leigh Sports Village, Leigh, England
Elland Road and Headingley Stadium Leeds, England
Ashton Gate Stadium and Memorial Stadium Bristol, England
Galpharm Stadium, Huddersfield, England
City of Salford Stadium, Salford, England
Thomond Park, Limerick, Ireland
Parc des Sports, Avignon, France
Racecourse Ground, Wrexham, Wales
Odsal Stadium, Bradford, England
Langtree Park, St Helens, England

I just hope the RFL use some common sense and put games in sensible places.

Wales games in Wales.
Fiji games in Rochdale. (large fijian community in Rochdale)
Aus and NZ games not involving England being played in London.
France games in France. (I know England are meant to be the hosts but the crowds would be brilliant in south France)
Ireland games in Ireland. (see above, and Irish venue has applied, we would be daft to turn it down)
Double-headers to cut stadium costs and increase crowds.

Open the tournament at Old Trafford/Wembley and the have the final at whichever stadium missed out on the opener. Obviously the opener should be England v Aus.

Semi-finals at Elland Road and Eastlands. Lets hope one SF is Aus v NZ and the other is England v Wales.

Bristol have invested alot into hosting some games so I say give them some good fixtures.

DO NOT make stupid decisions like some of these 2000WC fixtures...
Aus v Fiji in Gateshead??? Just no. It got a crowd of 4,000.
NZ v Lebanon in Gloucester??? NO. 2,000 in attendance.
NZ v Cook Islands at.. wait for it... the Madejski Stadium, Reading.... 3,000 attended.
QF - Aus v Samoa at Watford??? Really??? 5,000 people
QF - NZ v France at The Jungle... please don't use such poor stadiums in this WC, especially for big games. 5,000.

What would be the point?

My point would be that it will hopefully be part of a successful joint hull bid and with the links to PNG it would be able host one of there games at the stadium. For example PNG v Samoa in Group B. I think it would be very well attended and have a great atmosphere to go with it. Like Rochdale hosting a Fiji game for the same kind of reasons.

Would the links not be better used at the bigger ground? Getting all the people from Hull behind it and aiming for 20k?

Or shall we go into the wc thinking small?
