Apple may be planning a Hotel app for the iPhone — Apple World Today

Apple’s idea: using a single app, a user could access and control hotel services before arriving at the hotel, upon arriving at the hotel, in the hotel room, in the local vicinity, and after leaving the hotel. Such services can include, for example, checking-in and checking out, purchasing in-room dining or in-room entertainment, making reservations at local restaurants or local attractions, scheduling hotel guest reminders, and controlling the room setting either within the room or outside of the room.
