I've been playing with this new app...Glympse. It's a GPS location service which tracks your phone as you drive. It's great for giving people a "glimpse" of where you are and how long it might take for you to arrive at your destination...home, work, hotel, etc.
There are numerous possible uses in hotel operations. Perhaps a driver tracking method. Ever wonder when the airport driver will return to the hotel? How about someone making a delivery?
Anyway, give it a whirl. And, let me know how you end up using it.
