Marriott International has updated its app, making it a universal app for Windows 10 on PCs, tablets, and phones. The app allows you to easily check-in and check-out of hotels, enroll in Marriott's Rewards program, and more. Marriott now also features Cortana integration.
This is what Marriott has to say about its latest app update:
In our first 2016 release, we're excited to launch the upgrade of Windows 10 for smartphone, tablet and desktop. Also, we've integrated our app with Cortana and People Hub to make travel easier!
You can grab Marriott International from the Windows Store now.
