Soon we'll be able to bypass desk clerks when we check-in at hotels.

After testing a mobile app in several hotels over three months, Marriott has decided to allow guests to check-in with their mobile phones or tablets throughout its 329 properties in Canada and the US.

Marriott Rewards members are now able to download the Android or iOS app to check-in with their smartphones or tablets as early as 4 pm the day before their arrival and will receive an automatic notification when their room is ready. Upon arrival, guests simply go to the expedited mobile check-in desk where their key card will be ready and waiting for them.

The Marriott Mobile app has been downloaded 2.3 million times with additional towels, wake-up calls and housekeeping topping the list of guest requests. The hotel chain reports that it receives 10 million mobile visits per month to its site and mobile revenue is up 80 percent yearly to $700 million.

Paul Cahill, senior vice president of brand management for Marriott Hotels, adds: "We recognize our guests – especially Millennials – do not separate work and play, and travel enhances them both. They are more mobile and global than ever before, and technology – especially their mobile devices – keeps them connected to their world. We will continue to engage our guests to join with us on our journey to transform Marriott for next generation travelers."

In November, Marriott will be testing the mobile check-in app in 15 other countries, including the United Kingdom, China, United Arab Emirates, Mexico and India.
