Eeehop.com - Ok, I know, there are may European tourism sites offering bookings of hotels, holiday homes, campings, etc etc. But this one is worth mentioning: Eeehop.com Although their design is not that nifty, the Google addon-tool they are using is quite handy. They're using the option to draw polygones on a Google Map, to point out exactly the radius around a certain city. So for example, when one is interesting in a holiday house within a 50 km radius of Nice, the map shows many homes in that area, but a drown radius shows exactly what is within your wanted boundaries.
This is very cool, and I'm wondering: why don't more travel sites offer this?
