Claudia Howard, who owns the Boathouse Hotel, said she had taken a “substantial hit”.
“We’ve had 147 bookings cancelled. If you take an average of £100 a night, that’s £14,700,” she said.
“On top of that, you have their spends over the bar, breakfast or if they’ve had an evening meal, so actually we’ve lost considerably more than that.
“We also have coach parties and they go across to Ireland and had to cancel as well.”
She said the business also had to pay to roof damage caused by the storm itself.
“It’s good to know they (the ferries) will be going again so business will pick up. The one worry is, if there’s four ferries, there’ll be less cause for people to stay in Holyhead.
“But at least they’re going, and that’s a relief.”
She added the cancellations also had issues on supply chains, such as linen companies which supply the hotel.
