MapMyEvent is a Google Maps mashup that can automatically generate a map for your conference or event. All you need to do to create a map is to click on a location. MapMyEvent then creates a map with all the necessary hotel and tourist information at your chosen location.
The generated map includes driving directions, Street View, Wikipedia, photos, videos, hotels, and tourist attractions. Nearby restaurants can be viewed on the map, as well as upcoming events that are listed on Eventful, Zvents and Upcoming.
Each MapMyEvent map also comes with its own unique url.
