Road Trip - Advice and recommendations Sought

[jazzflask]

I am planning a roadtrip, departing Aberdeen on the evening of 24th of June and am heading to Dover for the Calais crossing and from there over to St Gallen, Switzerland to attend the Open Air festival www.openairsg.ch

After this event, we are travelling to Austria to Innsbruck ( I think ) then heading upto Prague, back across Germany & Holland to Amsterdam and back down to Calais for the boat home 2 weeks later.

This is a rough route which is still very much work in progress. I am looking to drive on some very scenic / dramatic alps roads and also a hurl on the Autobahn.

Can anyone point me in the direction to establishing a good route roughly around the boundaries I have stipulated as above?
