Title: Start mapping data, starting with hotels

You're probably looking at this list of hotels and wondering... where are these? Well wonder no more! Here's a geojson of most of the hotel venues, and thanks to Github's built in geojson viewer: instant map.

### how this works
for every venue, add the coordinates. You can get coordinates one of multitude of ways. Here's two:
* right click a point in Google maps and click "what's here?", then copy paste coordinates
* use some sort of geocoder

Note that you really have to verify the coordinates. Even with well known and long established venues, I had to refine my query and tweak map pins. A great tool for tweaking pins can be found at

I then wrote a [script](https://gist.github.com/crccheck/cdd007a7374310d3ba9d) to read hotels.yml and spit out a geojson file.

### how to use the geojson file
Github has a built-in viewer. Since geojson is a standard file, someone more industrious could also incorporate it. If we made geojson files for other venues, they could be combined into one map.

### next steps
* standardize the format of the yaml files so geojson files can be made easier
* decide if rejected places should get mapped
* document how to contribute coordinates
* check in script for generating the geojson so it's easier to update the geojson files
* is there a way to style the github map points?
