The boss of the pub chain said that rail strikes could cause Christmas parties to be canceled.
Staff who rely on hours and tips over Christmas could suffer if there is a wave of canceled bookings.
The sector can have the Christmas it deserves if the strikes are canceled, he said.
There were new strikes in the run up to Christmas.
The row over pay, working conditions and job security for rail workers will be held for 48 hours in December and January.
Mr Emeny said that the move could hurt trade in the Christmas season.
"We are all looking at this Christmas as a chance to trade well ahead of what will probably be a tricky winter and these train strikes are going to impact the hospitality sector - but more importantly, hospitality workers," he said.
If the train strikes continue, they will have hours cut and tips reduced. The train strikes are a problem for the sector.
He said that the hotel chain's Christmas parties and lunches had been very well received.
Customers have been told by the firm that it believes the strikes could be canceled.
"There's only so long we can delay those enquires about cancelling and really what we need is a quick resolution because people will have changed their plans by then," Mr Emeny said.
The strike action would send a clear message that workers want a better deal, according to the union.
More than 40,000 people are expected to take part in the event.
In the run-up to the strikes, the pub's parties and celebrations have been called off, according to Charlie Baker.
The business has been canceled.
Parties of up to 150 people have been canceled by customers. They can't do anything about Christmas being ruined for them. If it's not possible for your workers to get to the party, it's not worth it.
He said the loss of business was frightening.
With pubs, restaurants and cafes facing a "cliff edge" with energy bills set to go up further in the spring, Charlie says building up a buffer of cash is more difficult.
I empathise with the rail workers but it's really difficult for us as well.
It is a lucrative time of year for rail workers who make good tips and can work additional overtime because of extra demand from customers, according to a letter written to the transport secretary.
The impact of rail strikes so far this year has been devastating and wide-reaching, but this will pale in comparison to what we will see as a result of the upcoming strikes in December.
"These strikes damage all parts of society and it's now time for the government to come up with a solution that protects the nation's workers and customers this Christmas."
The Transport Secretary sent a letter to Mick Lynch, the union's boss.
"I want to work with you and employers in good faith to help resolve these long-standing issues, and help the employers and you reach a resolution that is fair to all."
He said that he wanted to make jobs on the railways rewarding for workers, and that he hoped this would allow for industrial action to be called off.
