古堡路和童话路上的几个小镇好玩么？

我初定的德国境内的自驾线路，几个问题一起请教一下大伙。


08/22 Basel, Switzerland -> Freiburg, Germany (据说黑森林里面挺有名气的小镇，有必要呆一晚吗?)


08/23 Freiburg, Germany -> Freudenstadt, Germany

08/23 Freudenstadt, Germany -> Baden-Baden, Germany (黑森林观景公路)


08/24 Baden-Baden, Germany -> Stuttgart, Germany (参观奔驰和保时捷博物馆)

08/24 Stuttgart, Germany -> Heidelberg, Germany (傍晚到，住一晚)


08/25 Heidelberg, Germany -> Rothenburg ob der Tauber, Germany (The Castle Road，游览Rothenburg需要几小时)

08/25 Rothenburg ob der Tauber, Germany -> Würzburg, Germany (The Castle Road, 游览Wurzburg需要几小时)

08/25 Würzburg, Germany -> Hanau, Germany


08/26 Hanau, Germany -> Steinau, Germany (The Fairy Tale Road，游览Steinau需要几小时)

08/26 Steinau, Germany -> Marburg, Germany (The Fairy Tale Road，游览Marburg需要几小时)

08/26 Marburg, Germany -> Bonn, Germany (波恩有没有趣的景点)

08/26 Bonn, Germany -> Cologne, Germany


08/27 Cologne, Germany -> Dusseldorf, Germany


路线有点紧，不知道古堡线和童话线上的几个小镇好不好玩，如果不值得去，我打算从Heidelberg直接开到Cologne，时间就宽裕一些。
