Weve been to all the places you mentioned several times over and you wont be disappointed.With 14/16 days youll be surprised how far you can get .We always stick to the rules of 250 miles/4PM on transit days and weve managed Slovenia and back taking in most of the good bits of Austria and the Dolomites as well in the time scale youre looking at without having any hard days .
Theres many more hotels/campsites but the hotels mentioned are two of the very best and well worth a visit just for the crack
Enjoy but remember you do it once and youll be hooked , weve been doing it for 20 years and still aint had enough
