Wasn't that long ago that the majority of travelling fans would go by coach. To suggest that so many now choose not to go because of issues with the train seems a bit implausible.

IMO the Final unfortunately just isn't a big enough occasion anymore for Wembley, and the RFL have only got themselves to blame. Magic has been part of the death, as well as Catalans inclusion in SL perhaps (how much money exactly do the RFL think the average fan has?!), as well as the increased importance and emphasis over the years of the Grand Final, which easily feels like a bigger and more important match these days.
Finally the timing is ridiculous; imagine being (for example) a Leeds fan in Sept 2015 having to find the money for Old Trafford a matter of weeks after likely shelling out tens if not hundreds for Wembley. The two games are just too close.
Principality Stadium in April or May, that's what I'd do. Last week's attendance in that 74,500 stadium would have looked miles better.

Never mind looked miles better I think it would have been better

Go back to playing early in the season without massive gaps between games. So that the excitement can build for supporters.

Think that's more important than the location.

I remember people at the time calling for the CC Final to be moved from May as early rounds were pretty much beimg treated as preseason warm up games by the full time clubs,and folk said that winning a trophy in May was pointless as it meant nothing come the end of the season. Plus it was competing for TV space with the 6 Nations and football.

So unless those issues are to be addressed somehow, putting it earlier in the calendar is unlikely to improve much.

I don't recall that but there seems to be a shift. Ultimately there won't be any time in the year where there isn't a clash with some sporting event.

I just think with changes to the league structure it could add something to the calendar.

Works in football with the league cup early in the season too.
