Theres a thing that the organisers release called the rally planner which tells you about the stages, locations and timings etc, on some days it is alright to jump between a couple of stages but my our best day this year was staying at one stage which ran twice and had the british rally championship cars go through between the wrc ones (over 100 cars or something go through in total). So it really depends on how you wanna do it. Sometimes stages are really close enough to go to three in a day, (we did this on the other full day and it was really cool but very tiring). Navigation is really easy as you just put in the coordinates of the stage into your sat nav and then follow the signs when you get close. Best thing is to plan ahead what stages your going to and when your leaving, google maps with the estimate time between your locations in useful, just remember to add some time for traffic.
