A new report, commissioned by Fáilte Ireland, has warned that Dublin faces a shortage of visitor accommodation over the next two years.
The Analysis of Visitor Accommodation in Dublin by consultants Fitzpatrick Associates found that rising tourism levels could leave the city's hotels and guest houses thousands of beds short of demand.
This could push up room prices and impact the city's competitiveness as a destination.
The report found that while there are plans for over 5,5000 new hotel beds in Dublin, most are not set to become available until 2018 at the earliest due to the lead-in time involved in developing or upgrading facilities.
Fáilte Ireland has suggested a number of short-term measures to try to deal with this issue. These include improvements to suburban transport links and regulatory changes to allow for smaller hotel rooms.
Fáilte Ireland's chief executive Shaun Quinn said that between 2010 and 2015, tourist arrivals to Dublin rose by 33%, but the stock of available accommodation actually fell by 6%.
"Given this stark fact, and with further visitor growth anticipated, Dublin's shortage of tourism accommodation may now be the biggest challenged facing the continuing growth of Irish tourism," Mr Quinn added.
