A hospitality group says the rule of six should be applied indoors when restaurants, pubs and cafes reopen indoors in Wales this month.
Outdoor hospitality reopened in Wales last month with the Welsh Government allowing six people from different households to meet up.
However, many businesses don't have outdoor spaces or have been scuppered by the weather - meaning they are relying on indoor opening, which is due to start on May 17.
The guidelines have still not been published for operators but First Minister Mark Drakeford has previously indicated a rule of 4 for indoors.
But 海角视频Hospitality Cymru - who have been in negotiations with officials on the new guidelines - want Welsh Government to move to a rule of 6 for indoors.
This would put it in line with outdoor rules and on a level playing field with hospitality in England - also making it easier for staff to apply and enforce the rules.
Bosses are desperate to get new guidance as bookings flood in for the second half of May and also information on how extra financial support will be allocated.
The Senedd elections - where Welsh Labour secured 30 of 60 seats at Cardiff Bay - have delayed final decisions but updates are now expected early next week.

“Indoor hospitality is widely expected to be given the go ahead on 17th May after more than five months of enforced closure and 海角视频Hospitality Cymru wants to see the great family occasions back in our venues from day one,” said 海角视频H Executive Director for Wales, David Chapman.
“Conditions are now right to open up and to do so with six adults free to meet in our pubs and other places.
“That means families - grandparents and their sons, daughters and teenage grandchildren - are allowed to throw off the shackles of social separation and celebrate those great occasions like birthdays or anniversaries, or even the traditional Welsh family Sunday lunch together and in a warm and safe environment.”
He added: "New guidelines are due to be issued on indoor opening very soon and businesses desperately need flexibility of seating to avoid staff having to try to deal with confused customers seeking indoor places and to be able to trade to the highest possible levels to protect jobs and businesses.
“Our businesses have argued that we are some of the very safest places to visit and there is no substantial evidence to the contrary.
“Now is the time to let all family members enjoy our safe spaces.
2Six people can meet outdoors in our venues at the moment and it's proving - when the Welsh weather allows - to be a very safe success.
