Furkot is a road trip planner. It does things that you used to do with a road atlas and a bunch of post it notes. Or - more recently - with a spreadsheet and a bunch of websites displaying maps.
Different trips call for different trip planning process. You will find couple of pointers to get you started here. You do not need to follow this process though. Great thing about computers is that they do not mind doing stuff over and over again. So start small, add a few stops, find a lodging or two, add more stops, and then some more lodgings. Continue until everything looks good to you. Furkot is flexible. It will try to work with you.
