What Google Maps is best at for trip planning
Google Maps is the fastest way to answer geography questions. Where is this neighborhood? How far is the airport from my hotel? Is it even reasonable to visit two attractions on the same afternoon? For early research, Maps is hard to beat because it gives you instant context and you can save places as you browse.
Maps also shines when you want to see the shape of a day. A quick route preview can reveal that your wish list is spread across town, or that a day trip is longer than it looks. If your planning style starts with pinning restaurants, viewpoints, museums, and cafes, Maps is a natural home for that collection phase.
