Drunken behaviour and tensions around parades has hit the promotion of 12 July as an 'Orangefest,' in Belfast, a report has said.
Since 2009 many retailers in the city centre have opened on 12 July, when the Orange Order celebrates William III's victory at the Battle of the Boyne.
However, the Belfast City Centre Management report said trade was hit heavily this year.
BBC Northern Ireland business correspondent Julian O'Neill reports.
