Phipps,
They are rugby fans first and foremost with the international team playing hundreds of miles away along with the local regional team that weekend.
You say that Cardiff Central train leavers do not bottle neck. I move through the same ticket barriers every day along with thousands of others and have been approached by dancing noses handing out tissues, tiger tiger staff handing out leaflets weekly and various other weird and wacky ideas aimed at the 'non bottlenecked' punters.
The picture shows 4 sets of doors, three of which are dead central ahead of the main ticket barriers. There are two to the left but the outer doors are used very little and are sometimes locked. Anyway my point is most come through these doors and if we target this area which people must walk across to get to restaurants, work and various pubs and clubs we will benefit. If anybody that lives and works in Cardiff can verify this to be the case that would be appreciated.
Fans going home will not be as important as they will have already missed a days rugby and if they haven't taken up the offer on day one to take the going home option they probably won't return so it's better to target new fans with a straight head (at the time) and full wallets.
If the RFL move quickly they will be able to appeal to 70,000 plus watching Wales-England in the city this coming Friday. I'd go as far as getting leaflets advertising the event and pointing them to ticketline on Westgate Street that will be selling the tickets.
Come on RFL, do this one thing and you will reap the rewards.
