You will need a smart phone to get to your hotel room

Hilton is going mobile. This is a big deal. 80 countries, 4 000 properties, 650 000 rooms, and you will be able to book online, customize your room and unlock the door. This is a $500 million project.

It points to the fact that the penetration of mobile devices is such that they expect guests have a smart phone. Hilton is also, with this move, trying to remove any middleman in the booking business. Hilton will have direct access to you, will know your preferences down from the type of music you enjoy to the level of light in your room, everything.
