A Cardiff city centre hotel has had to shut four of its floors at the last minute due to "maintenance work".
Premier Inn on Churchill Way has cancelled bookings after 52 of its rooms were affected.
Some of the customers believed to be affected are those who had booked to stay for the Wales v England rugby match on Saturday on what is expected to be one of the city's busiest weekends of the year.
An email seen by WalesOnline which was sent to a customer by the hotel's management team said its "safety team" decided the top four floors of the building needed to be shut.
Premier Inn said it hopes the affected rooms will "be up and running in a few weeks". But when asked about the nature of the work needed to be carried out, Premier Inn was unable to provide any other information.
It was also unable to confirm how many customers have been affected as they are "unsure" how long the closure will last.
A spokeswoman said its safety team oversees any maintenance issues.
It is understood that Premier Inn told some customers it was unable to honour their bookings at Churchill Way this weekend and instead offered them rooms at the chain's hotel in Caerphilly.
One customer, who did not want to be named, said they booked a room at the city centre hotel between four and six months ago specifically for Saturday's rugby and paid £68.
They said: "I received an email [on Tuesday] saying that they had some essential maintence. The only place they could offer was Caerphilly and thought this is totally unaceptable. "
An email from the hotel to the customer dated August 13 said: "I do apologise for this inconvenience. Unfortunately the maintenance work was bought to us at the last minute. It is something out of our control regarding the building we rent and after speaking to our head office and our safety team it was decided that we had to put the top four floors out of sale.
"As you can probably guess with it being such a big weekend it has caused us as a hotel some inconvenience."
The email adds that if the customer wanted to book another hotel in Cardiff it would cancel their booking free of charge. It said they could not book them into another hotel or cover the cost.
The customer said they later received an email on Wednesday stating their booking could now go ahead as planned.
According to property firm Knight Frank, the ten-storey hotel was built in the 1980s and "comprehensively refurbished" in 2009.
A Premier Inn spokeswoman said: "We apologise for any inconvenience caused and we are working directly with affected guests to help minimise disruption."
