The already delayed opening of the Rocco Forte hotel in Abu Dhabi has been pushed back to October.
The decision puts it in direct competition with at least half a dozen rival luxury hotels planning to launch in the capital by the end of the year.
Other five-star properties aiming to open their doors after the summer include the Park Hyatt and St Regis hotels on Saadiyat Island, the Eastern Mangroves resort, the Jumeirah Etihad Towers hotel, the Hyatt in the leaning Capital Gate building, and the Westin at Abu Dhabi Golf Club.
"It does sound quite challenging that so many new hotels will come at the same time, knowing that there are more to come next year," said Hagop Doghramadjian, the general manager of the Dh600 million (US$163.3m) Rocco Forte Hotel Abu Dhabi.
"There will always be competition but that should not stop anyone from opening. Any destination needs a good range of hotels to make [it] even more known and more attractive."
Analysts said the opening of the hotels would be keenly watched given hotel performance in Abu Dhabi over the past 18 months.
Mr Doghramadjian said the hotel had delayed its opening from June because it did not make financial sense to open in what is the low season in the UAE. It would also allow more time to get the property ready, he added.
"Obviously, every hotel wants to open when the season is right," Mr Doghramadjian said. "We all know that the summer is a slow season for the UAE. We bought time to have the project finished in a perfect way, rather than rushing it.
"Then we have more time to get organised with our recruitment plan and our opening time. We'll launch the hotel when people are back from their holidays."
The hotel, which has 281 rooms, is expected to be open by early October, but could launch by late September, Mr Doghramadjian said. The hotel is about to start recruiting about 400 staff.
Rocco Forte, which has hotels including the Balmoral in Edinburgh and Brown's in London, has agreements to operate properties in Cairo, Marrakech and Jeddah. Last week, it announced plans to help refurbish and then operate the Luxor Hotel in Egypt.
The company is owned by the son of the late hotel magnate Lord Charles Forte, who owned Forte.
Mr Doghramadjian said he was confident about the long-term potential of Abu Dhabi as a destination, as events including the Formula One Grand Prix, conferences and the cruise industry, was bringing more visitors to the capital.
"Abu Dhabi is an emerging city, which has major development plans for the next 18 years," he said.
