As part of its global mobile strategy, Marriott International has revealed a significant expansion of the company’s mobile check-in and checkout feature.

Now, eleven additional brands are joining the nearly 500 properties of the company’s flagship Marriott Hotels brand in providing mobile check-in and checkout to guests.

Brands include The Ritz-Carlton, JW Marriott Hotels & Resorts, Renaissance Hotels, Autograph Collection, AC Hotels, Courtyard, SpringHill Suites, Fairfield Inn & Suites, Residence Inn, TownePlace Suites and Marriott Executive Apartments.

With these latest additions, these services are immediately available at 1,200 properties worldwide, and will be live at more than 4,000 hotels worldwide by year-end.

Marriott is laser-focused on delivering the mobile services travellers told the company that they want most and making these services as widely available as possible.

The company is rapidly introducing mobile services that improve the travel experience by giving guests added convenience and greater choice, while giving hotel staff the opportunity to deliver an even higher level of service.

When it comes to fulfillment, the company’s hotels have achieved a near perfect success rate in executing a half-million mobile check-ins to date, leading to nine out ten guests saying they will use it again.

With the Marriott Mobile app, check-in and checkout is simpler.

At the end of their stays, guests receive a push notification alerting them that mobile checkout is available.

Upon completion, guests will then be prompted to provide an email address where their bill should be sent, allowing them to confidently bypass the front desk.

Mobile check-in and checkout are available in five languages:  English, French, Spanish, German and Mandarin.

Leading with its flagship Marriott Hotels brand, the company continues innovating in the mobile space.

The brand now offers mobile service requests in fifteen markets in North America, where hotels are serving as “mobile incubator” laboratories for the future.

For example, guests at these hotels can use a drop down menu of the most typical service requests, such as extra towels and pillows, or chat directly with hotel staff using a mobile app.

The company will offer these and other mobile services to its Marriott Rewards members at the Marriott Hotels brand beginning early next year.
