Room 77 can help you book the hotel room with the best view. Using some pretty smart algorithms Room 77 is able to show you the view from different hotel rooms using images captured from Google Earth.
Using Room 77 you can check out the views from rooms in hotels in a number of US cities and in London. To show you the view Room 77 calculates the latitude, longitude, altitude and orientation of the room and shows you the view as seen in Google Earth. User submitted photos are also shown where available.
Room 77 uses Google Maps with an overlay of the hotel to allow you to see the view from different rooms within each hotel. The overlays allow you to select different room numbers and even allow you to select different floors in each hotel.
Room 77 even has its own ranking system for hotel rooms based on your individual preferences for view, floor, distance from elevator and connecting rooms. Each room is then shown on the Google Map with a color-coded match percentage indicating: "strong match" (green), "fair match" (yellow) and "weak match" (red).
