It was revealed on Monday that the Irish foursome will take to the stage at the Cork stadium on Friday, August 28.
The event, which has been described as a “win-win” for business in Cork, is expected to draw tens of thousands of fans to Leeside.
Tickets go on sale this Friday and a second night at Páirc Uí Chaoimh has not been ruled out.
Hotel rooms in Cork are expected to sell out fast after the tickets are snapped up and there have been calls for hotels to maintain their original prices for the night.
Cork city councillor John Maher (Labour) has called on hotels across the city and county to suspend their algorithms hiking prices for the August 28 gig and not gouge people coming to Cork for the Westlife concert next year.
“This gig will be huge for Cork,” he said.
“We cannot be seen as a destination that rips cash from people’s hand over fist. This will be a boom for Cork — there’s no need for prices to increase rapidly and it would be a signal that Cork is value for money,” he added.
“Suspending the algorithms removes any doubt that hotels are prices are unfair. Let’s show Cork in a great light next August.”
Westlife’s show, which is to be their only stadium outing in Ireland next year, is expected to attract tens of thousands of people to Leeside in 2020.
“It was very clear to see the economic benefit that Rod Stewart brought to the region last year, and particularly Ed Sheeran the year before, so we’re thrilled at the announcement,” said Lawrence Owens, chief executive of the Cork Business Association.
Ed Sheeran’s three concerts in Cork were worth an estimated €60m to the local economy.
“Anything that can draw additional footfall to the city is fantastic because the spin-off will reach all sectors — everybody wins,” added Mr Owens.
