Admirable level of Dublin arrogance exhibited there folks.
"Very few are interested in Belfast" is a line taken directly from Paddy Goebbels Guide to Marketing the island of Ireland!
Of course no Dubliner is going to encourage visitors to go to Belfast. That is why the present system of external marketing is such a farce.
Futile as it is to elaborate I'll merely mention Titanic (The World's Best Visitor Attraction), the Giants Causeway, Game of Thrones, British Open Golf at Royal Portrush (2019) - for starters.
No one is suggesting people don't want to go to Dublin. It's just that they don't ALL want to go to Dublin, whether they're coming from Britain where their £ is worth the same in Belfast, but not in Dublin - or indeed from New York or Toronto. But the way things are set up, visitors are effectively being corralled into Dublin, whether they like it or not.
If Dublin was 'all that' perhaps Mr Cowen would not have produced such a creditable impersonation of Oliver Twist in Brussels, Berlin and London a few short years ago?
Let's see what transpires.
