A recent NYT article got me thinking about travel apps and I thought I would see what apps Insiders recommend. Searching the MRI site I also found a Dec 2012 blog post from vaboywnder on this topic. (Great Travel Apps)
I use the following apps: Kayak, Google Maps, OpenTable, Uber, and TripIt to either help plan travel or make my trip more enjoyable.
What are the apps that you find most helpful when traveling (or preparing to travel)?
