Google Maps for iOS and Android have been updated with Gmail integration, allowing users to see their flight, hotel, and restaurant reservations within the Maps section of the app.
Like Google Now, integrating with Gmail lets the service trawl through relevant (but for marketing purposes, anonymized) user data, displaying travel information when the user comes within the vicinity of various landmarks. While it seems that the integration is limited to the U.S. for now, Google plans to roll it out to international users shortly.
Google has also added Santa’s Village integration to the app, a basic Santa Tracker built in HTML5. Users can play various mini-games and spend time with the big man and his elves in a cartoony, virtual environment in the run-up to Christmas.
