Hi, Christine!
The newer versions of the maps available on Walt Disney World's website have a bit more information on them than the older ones, so take a look at what's online now for more specific information. You'll be able to view a
map of Main Street U.S.A., including names of shops and restaurants, simply by zooming in until the names appear on the map.
In addition to this, according to the unofficial site wdwnewstoday.com, new Walt Disney World Park maps will be released on March 3rd. While this information is still unofficial, the above-mentioned source states that these maps will work more smoothly with the My Disney Experience app, which is currently available for no charge for smartphones. On that app, the same type of information you can now find on the new Walt Disney World website is also on the maps in your smartphone. I just love the detail!
Send more questions as you think of them, Christine; we love to help!
