One Direction fans really are a hardy lot.
They came prepared with chairs, blankets, sleeping bags, pop-up tents, and single gas burners in order to ensure that they got a chance to buy concert tickets.
First in the queue at Castle Place, Belfast, was Zoe Buchanan from north Belfast.
The 34-year-old was up early yesterday morning to ensure her place in the line in order that her only daughter Katie (10) would get a ticket.
She was prepared to brave the cold in order to make sure that her daughter was not left disappointed after she failed to get her a ticket for last year's One Direction concerts in Croke Park, Dublin.
"I've never done anything like this before but Katie just loves them and I don't want her to be disappointed."
Kate, who's a Zayn fan, later joined her in the queue.
Next to her was Anne Grierson from east Belfast, who was also prepared to camp out in order to get tickets for her daughters Kaiesha (16) and Katie (12).
"The tickets are for the girls, I'm more of a Daniel O'Donnell fan, but it's been good so far," she said.
However, she was not expecting her daughters to join her in the queue. Mother and daughter Michelle and Victoria Hamilton from north Belfast wanted to get four tickets as Victoria will turn 15 on the date of one of the concerts and intends to go along to the concert on her own with three friends.
