The group responsible say they are "completely changing" how it's done
The Christmas lights in Dublin city, including Grafton Street, are being switched on on Sunday November 19th.
But business group DublinTown say they cannot reveal exactly what is planned until details have been finalised.
Clyde Carroll is director of marketing and communications for DublinTown, who put up the Christmas lights.
He says: "Coming into town to see the moment the Christmas lights get switched on, which marks the official start of the Christmas season, has always been a thing for families and friends to come in and experience.
"But in recent years it has grown into a huge occasion in the city and last year an event on Grafton Street was planned to cater for a crowd based on previous attendance but the crowd that showed up far exceeded our expectations and plans."
Mr Carroll says they are completely changing their approach this year.
"Having fully analysed what happened last year, we are completely changing how the lights will be switched on in the city to accommodate more people and make it a more comfortable experience for all, especially young children.
"We have spent the past few months working on the plan with all city stakeholders and our partners on Dublin At Christmas, Dublin City Council," he said.
