The plea comes one week ahead of the Welsh government review, where first minister Mark Drakeford is expected to update the nation on the easing of restrictions.
The group believe that Welsh officials should follow the UK government’s move to fully remove social distancing measures on 19 July.
According to UKHC, this decision will help businesses in Wales to manage the “huge influx” of summer visitors.
David Chapman, executive director for UKHC, said: “On July 19 we’re expecting England to fully open up and from that moment we need to make sure visitors to Wales are welcomed with a set of simple directions about how to stay safe and enjoy their holiday while they are here.
“Welsh government ministers are suggesting we have to now learn to live with the virus; it’s time to make it simple and easy for those looking to take their first restriction-free break in eighteen months.”
He added: “We don’t want hospitality workers to be at the receiving end of visitor confusion, disappointment or annoyance about what can or can’t be done; let’s make it as straightforward as possible.
“Open up now, stay savvy and stay safe. They should be the watchwords of the new normal of living with Covid-19 in Wales in a post-vaccine environment.”
