Sir, – Congratulations to the GAA on its initiative in setting up the rooftop walkway to view Dublin, but at €25 it is surely “a bit steep” (Home News, May 24th). Recently I spent an enthralling two hours at the Titanic Experience in Belfast. Ingeniously conceived and brilliantly executed, the Experience cost me under £13. God be with the days when you could view Dublin from the top of the Pillar for a tanner! – Yours, etc,
