I am a huge advocat of having the CC semis as a double-header. Not sure about Millennium Stadium, but if they offer us money again (hint hint Welsh Tourist Board!
) I would be strongly for it. Surely a game as big as the semi-finals will bring in a lot of fans if played at somewhere more exciting than bloody Huddersfield! Add that the number of interested locals and could be on.
WTB obviously want the business. I doubt they'll get the same number of fans coming down as MM over the full weekend, but reckon it will be at least as full (if not more full) than either day of MM. I'd not open the top tier, though. Middle and lower tier only. Middle tier reserved, bottom tier unreserved.
If they do it though, announce it now and not after the semi-final draw has been made so neutrals can plan for it!
