The uncertainty about how the rising Covid case numbers and hospital admissions will impact on the remaining restrictions is being felt by those planning large events and weddings.
From 22 October, it had been anticipated that the 100 guest limit for weddings would be lifted and capacity restrictions for other indoor events would also be eased.
The InterContinental Hotel in Ballsbridge has spent the last number of weeks planning to host gatherings of hundreds of people.
Its director of operations said that people's livelihoods will be at stake if these events are not permitted to go ahead.
Doiran Kavanagh said that the hotel has been contacted by concerned couples due to get married in the coming weeks.
"Couples are really concerned, but unfortunately we don't have the answers for them," he said.
He said they would be expecting all their friends and family attend, but there is a great deal of unknown still.
"Wedding numbers are not going to go back to what they were pre-pandemic, but certainly couples were hoping to have a lot more than 100 guests. Here at our hotel we can cater for a great deal more.
"The restrictions on live entertainment, and bar service plays a huge part in the night of a wedding and the post party. The fact that’s in danger or in jeopardy is a great concern to our couples," he said.
He said the safety of staff and guests is the hotel’s priority and it will abide by whatever restrictions are in place at the time.
Mr Kavanagh said the hotel also has a lot of corporate clients who would have been planning large Christmas parties for their staff for many hundreds of guests, but they too are worried about what may happen this week.
"Those clients are concerned that if they can't host those numbers they may not take the event at all. Restricting numbers in an office environment where you may have 1,000 employees, down to 100 is very difficult."

'Give nightclubs a chance to reopen safely as planned'
'Groundhog Day' for the nightclub sector
A Dublin nightclub boss has described the latest uncertainty about the easing of Covid-19 restrictions as "Groundhog Day".
The Lost Lane venue and club in the city centre will have been closed 585 days by the time the 22 October comes around - the day the remaining measures are expected to be lifted.
However, a recent spike in the number of new cases of Covid-19 and an increase in hospital admissions has cast doubt on this.
Lost Lane director David Morrissey said that reopening should happen given Ireland's high level of vaccine uptake.
"Ireland has one of the biggest vaccine uptakes in the world. If we are not going to get open now, can someone tell us when? When is that? Because we have done absolutely everything that has been asked of us and now we find ourselves back in some form of Groundhog Day. We really need to get open and we really need the business for the last few months of the year," he said.
Mr Morrissey said that nightclubs like his need the remaining restrictions around social distancing like table-service only, and no access to the bar area, to be lifted.
He is also the vice chairman of the Licensed Vintners Association (LVA) and said that members are all "very willing" to implement the use of Covid vaccination passports for entry to hospitality, if the Government decides to extend this measure.
However, he said that he does not believe the use of antigen testing for the night time economy is viable.
He said preparing to reopen next Friday is not without its challenges as it has been "next to impossible" to fill a roster with staffing issues.
But he also said that there is now uncertainty among the companies providing security about whether their staff will come off the pandemic unemployment payment to return to work while there is still such uncertainty about the reopening next week.
Mr Morrissey added he is hopeful that the National Public Health Emergency Team and the Government will engage with the nightclub industry on this.
"We are very willing to engage but please get us open," he said.
He said the decision due from Government on Tuesday does not give the industry enough time.
"We really call on NPHET and the Government to look at our sector, to look at how willing we are to do {vaccine} certs and to get us open."
He said 349 pubs in Ireland and 33 pubs in Dublin have closed since the pandemic and "that number is only going to increase".
According to the Vintners' Federation of Ireland (VFI) and LVA the revelation of a 5% drop in pub licence renewals is a dramatic escalation in the crisis faced by pubs.
The figures were taken from an analysis of licence renewals published by the Revenue Commissioners.
"If we don't get open we are looking at a very downward spiral for the nightclub industry," he said.
