Fans of Harry Styles have been warned not to set up camp outside a venue before the singer's performance the following week.
As part of his world tour, the singer will perform twice at Cardiff's Principality Stadium on June 20 and 21.
To get the closest possible view of their favorite performers, devoted fans frequently camp overnight outside of venues.
Camping outside, however, is "strictly forbidden," according to a stadium spokesperson.
Instead, they advised the audience to find alternate lodging in advance and stated that waiting in line would only be permitted on the day of the performances.
Cardiff initially only had one concert, but after that date was sold out, another was added.
The support act will also include the Grammy-winning group Wet Leg.
In order to get a good spot inside the stadium when gates opened for Beyoncé's performance there in May, many people camped out overnight outside the venue.
The 25-year-old Cardiff resident Kristina Dummigan obtained tickets for both of Harry Styles' performances there as well as one more in Portugal.
She spent £300 on a first-night pit ticket in the hopes that it will allow her to get close to Styles.
She said, "I try not to think about that.
We'll have a more laid-back evening on the second night, just like in the stadium's back.
"The concerts are a ton of fun, and the stadiums are filled with a lot of good energy and stuff. Everyone is there to enjoy themselves. ".
But she emphasized that she would not be staying out overnight.
Going during the day is preferable because you'll be more prepared and able to enjoy yourself more, she said.
People who camp outside of concerts and other events are subject to some stigma. But I suppose it's just for entertainment purposes; people like to be around others who are anticipating the same thing. " .
Last year, when Styles performed in Manchester, fans came all the way from the US, France, and Spain.
In order to get a good spot in the crowd, some people camped out for three days in a line.
