Failte Ireland is writing to hotels nationwide to warn them about continued price-spiking.
The tourism development authority is encouraging businesses to be mindful of the reputational damage price-spiking could cause to Irish tourism.
The term price-spiking refers to hotel prices being raised when dates coincide with major events.
Lorraine Sweeney, a businesswoman and owner of three hotels in North Wicklow, thinks Failte Ireland is wrong to send out a warning.
