Speaking as one who has caught the train from Woking to Honiton, and the bus from Honiton Railway station for the last two years - yes it is perfectly possible to align the train and bus (which takes 20 minutes from Honiton to the stop outside the Volunteer - my stopping off point). The bus stop is immediately outside the exit from the station, so no long walk involved. Check the times of your trains into Honiton, and align with the bus timetable, and away you go .... no problem at all. I can't speak for the link up with the campsite bus, as I don't camp (shudder) ... :-)
