Our trip in April/May is settled except for a decision on how much time to spend in these two places.
We will be driving from Kotor to Saravejo for a 2 night stay and then to Mostar for one night before heading to Split. My thinking was to take the longer drive from Kotor to Saravejo first and then an overnight in Mostar to break up the drive to Split. I do have this niggling thought that we should just do a stopover in Mostar on the way in or out of Saravejo in order to get 3 nights in Saravejo instead of two. I have been back and forth several times and figured those with experience of both might be able to shed some light on this decision.
It might help to know our driving plan: Day trips are planned from base cities.
Dubrovnik 3 nights
Kotor 3 nights
Saravejo/Mostar 3 nights between them
Split 3 nights
Plitvice 1 night
Ljublyana 4 nights
Rovinj 4 nights
Zagreb 2 nights
Bus to Budapest for 5 nights
Flight to London for 1 night before a stopover in Iceland for 4 nights before flying home.
