For an ED, the distance and length does not matter...
(Sorry, couldn't resist!)
you can put 1 miles on the car, it's still ok!
to OP, there are millions of combination possible... you can do whatever you want...
it's up to you... take a chance and design your own trip...
do you really want us to spoon feed you ?
What's to fear ?
in nine days, you can very well be visiting 9 different places,
or just 3 places, it's entirely up to you, whether you want to drive/walk/ride the train/bike/sail on the Rhin/or fly!
Why dont you give it a try in designing your own trip?
What do you like to do? what would you like to see?
Can you dream something up ?
why would you want to live my dream?
why would you want to do what i tell you to do?
I could tell you what to do, but i would be too jealous of you living my own dreams!
