The owner of Llandudno Pier has warned that keeping the five mile travel guideline over the summer would lead to "mass redundancies" at the historic attraction.
First Minister Mark Drakeford has said the guideline - designed to prevent the spread of infections - could remain in place for up to 12 weeks depending on the progression of Covid-19.
But it has sparked huge fears in the tourism sector with UKHospitality saying up to 40,000 jobs are at risk this summer.
Pier boss Adam Williams says as workers are eased off furlough in the summer they may be forced into a spate of redundancies and put annual maintenance on hold if visitors can't travel to the attraction.
He said he had taken the last announcement about non-essential retail preparing to reopen as a green light to start getting ready to open the site, which employs 200 workers in the summer season.
He said: "I decided that in relation to Llandudno Pier I was ready to act on his advice and planned to open up all the takeaway food outlets and open the pier in a limited and safe capacity.
"We have therefore taken some staff off furlough and spent time rearranging the front kiosks to help abide by social distancing I have also spent a significant amount of money on PPE and other associated items to help people remain safe.
"I was extremely disappointed to read the First Minister's comments that the five mile travel restriction will remain in place in Wales.
"The five mile restriction means that really only people from Llandudno and the immediate locality can attend.
"I accepted the fact that the hotels would remain closed and that my family entertainment centres would remain closed for the meantime but by imposing this five mile restriction the Welsh Government are preventing us from receiving North Wales based customers who have planned annual leave and money in their pocket to come out and have a daytrip in Llandudno and give the tourism trade some much needed income.
"I have already accepted many losses in 2020 but now I feel like the Welsh Government is twisting the knife by not allowing us these small changes that could mean that we have some money to pay wages and carry out maintenance. I was fully expecting the distance to be increased to 15 or even 20 miles, this would have made a huge difference to us.
"As the situation stands at the moment come 1st August with the changes in the furlough payments we could be forced to make mass redundancies as with the information that has been provided by the Welsh Government we are unable to see how we will be able to open any of our businesses in 2020 with no clear road map or provisional dates it is impossible for us to make plans."
He said essential maintenance costing £300,000 had already been halted due to coronavirus and that he may not now have the funds to carry it out this year.
He added: "It leaves us praying that the winter weather isn't too severe otherwise there may be no pier left to start 2021 with. In relation to maintenance on a pier if it is left it gets worse very quickly and the costs can rise significantly as time goes on.
"I urge the Welsh Government to reconsider their position on the five mile travel distance I would also like some clearer direction on family entertainment centres, pubs and restaurants so that we have something to work towards no matter how far in the future.
"As it stands at the moment all that I feel is confusion and frustration at the lack of direction being given to people like me by the Welsh Government."
Mr Drakeford this week said he could not be certain if the five-mile advice will be still be around in “another six or nine or 12 weeks”, as this will depend on the progression of the disease.
Mr Drakeford insisted caution was the best policy.
Even though new Covid-19 cases had fallen from a high of about 400-a-day at the start of the lockdown, to around 50 new cases now, Wales couldn’t afford to drop its guard, he said.
Welsh Government has said it has "absolute commitment" to the tourism industry in Wales.
UKHospitality says an orderly and clearly signalled opening date that allows high summer season trading could save as many as 40,000 jobs this year in and around Wales’ hospitality industry.
