Hilton Worldwide has introduced digital check-in and room selection technology across 4,100 hotels worldwide, including 119 in the UK and Ireland.
The scale of the digital roll out across 11 brands is believed to be the largest of its kind in the hotel sector.
Through their Hilton HHonors accounts, guests will be able to check-in and choose their exact room from digital floor plans on desktop, tablet and mobile devices. They will also be able to request upgrades or make special requests regarding their room.
Geraldine Calpin, global head of digital at Hilton Worldwide, said, "Digital check-in and room selection puts our guests in the driving seat and gives them unprecedented choice and control across their entire stay.
"Never before have guests been able to check-in, select their room from a digital floor plan and customise their room ready for arrival. We are truly revolutionising the industry and this is just the tip of the iceberg for digital at Hilton Worldwide."
Last month, Hilton Worldwide announced that mobile key technology, which gives guests the ability to unlock their hotel room doors with their smartphone and to go straight to their rooms upon arrival, will be available in the US across four of its brands in 2015 - Hilton Hotels & Resort, Canopy by Hilton, Waldorf Astoria Hotels & Resorts, and Conrad Hotel & Resorts. By the end of 2016, this technology will be available across the majority of rooms worldwide.
Hilton Worldwide comprises more than 4,250 managed, franchised, owned and leased hotels and timeshare properties, with more than 700,000 rooms in 93 countries.
