Fianna Fail has said it would aim to bring eight million visitors a year to Ireland by 2015 under its plans to boost tourism.
Party leader Micheal Martin said such a hike had the potential to create up to 15,000 jobs in the hard-hit sector.
"We recognise that the tourism industry is a labour-intensive sector that will provide job opportunities and foreign revenue earnings as the economy recovers," he said.
"Our priority now is to continue to invest, upgrade and promote the tourism sector in order to take advantage of recovery."
Mr Martin said Fianna Fail, if returned to power, would look at airport and port charges, immigration and visa arrangements as well as marketing support for airlines and ferry companies as a way of increasing the number of overseas visitors.
His party would help cut costs in the homegrown tourism industry and create better access to much-needed credit for businesses, he claimed.
Launching his tourism strategy in Ballina, Co Mayo, Mr Martin said the arts and culture were also important to the creation of jobs as well as boosting tourism figures.
"Fianna Fail values the positive contribution that a thriving arts and cultural sector makes to Irish society as a whole and is particularly conscious of the potential of the sector to provide opportunities for self-expression and participation that can help lift people's spirits in a time of economic difficulty," he said.
