Marriott emphasized that they have 3300 hotels active with mobile room keys and more being added. This means not having to check in at the front desk with an employee, or having the employee handle your room key. Instead you check in with your phone, and use your phone as a room key.
That’s great, and Marriott is proud of how widespread this feature is (though not yet at half of their hotels). What they didn’t tell you, it turns out, is that they’ve actually pushed back the roll out of this technology at hotels which don’t currently offer it in order to save money.
