The tourism industry in Wales is facing the equivalent of three winters in a row, according to the Welsh Government.
Tourism is estimated to be worth £3 billion to the Welsh economy.
It comes as the Welsh Government has urged people to stay away from tourist destinations and beauty spots while lockdown rules remain in place in Wales.
Rebecca Evans MS, Finance and Minister for Wales, said: "I'm particularly concerned about the tourism industry here in Wales, I'd like to see the level of funding through the continue at a high level for that sector.
"They're telling us that they're basically facing the equivalent of three winters in a row, which is obviously concerning for business.
"The UK Government I think has done really well with the Job Retention Scheme, that's something that we very much support.
"But I think looking forward it's really important that they consider the needs of Wales in that.
"We rely very heavily at the moment on the Job Retention Scheme, so it would be really unfortunate if it were to end in a way, which didn't, for example, give people the flexibility to come back on a part-time basis."
But Downing Street said extra bank holidays “come with economic costs”.
Patricia Yates, acting chief executive at Visit Britain, said 2020 has to be the “year of domestic tourism” but there will be a serious challenge in convincing people it is safe to travel.
Prior to the coronavirus pandemic there were big plans to develop Wales' tourism industry.
It said the value of domestic tourism grew by 14 per cent last year.
