德国4晚4天的行程求教

全家去德国玩， 小的10岁， 共4天4晚， 打算driving along romatic road, we want to invite all the experts here to kindly give us some suggestions,

we first arrive at Munich airport around 4:00pm,
we want to visit Linderhof, Fussen(castls), possible Bercheshgarden, then along the romatic road to Dinkel*****uerg, Nordingen, Rotheburgen, werzbuerg
we then leave Werbuerg at 5:00pm

I am not sure how to best arrange where for our 4 nights stay and 4 days journey .

your suggestions would be valuable for us and would be very much appreciated
