Sunwing Arguineguin has been closed for the past two months during what is the third stage of a four-year refurbishment programme at the 252-room property, due for completion next year.

The €13 million investment has so far seen most rooms, bars and restaurants renovated, with the hotel also benefiting from investment in sustainable energy technologies such as solar panels.

Next year, works on the final set of rooms, a new a la carte restaurant and bar will be completed, which Cook said had been informed by guests’ demands for more upmarket dining options.

Cook said the renovations at the beachfront hotel on Gran Canaria’s south-west coast underlined its commitment to Spain, which remains its number-one holiday destination.

The hotel, one of Cook’s most enduring, still runs year-round with an occupancy rate of around 98% employing nearly 200 people, some of whom have been working there since it opened.

Cook announced a fresh €40 million investment in its own-brand hotel operation last month at the launch of its new Cook’s Club Palma Beach hotel, which Cook said would “cement its position as one of Spain’s top five international hotel chains”.

Last year, Cook launched a hotel investment joint-venture with Swiss investor LMEY, which has now grown to include nine properties and has secured more than €90 million funding from banks in Spain and Greece.
