OK thanks to all the useful info I got on this thread I've now heavily revised our trip planned for Sept/Oct 2022. Focussed in or Balkans
To recap - this between 2 cruises which arrive/depart from Barcelona. We've been to Barcelona before and have reserved a couple of days in that city each end. This was my first attempt https://community.ricksteves.com/travel-forum/general-europe/6-weeks-barcelona-return-to-eastern-europe-itinerary
fly Budapest (5 nights)
Train Subotica ( 1 night or day trip - depends on timings)
Train Novi Sad (over night)
Train Belgrade 2 nights
Fly or night train Skopje (3 nights)
Ohird (2 nights)
Tirana (2 nights)
Berat
Kotor (5 nights)
Dubrovnik (2 nights )
Mostar (1 night)
Sarajevo (2 nights)
(can't work out how to avoid backtracking to)
Split ( 3 nights)
train to Zagreb ( 3 nights)
Ljublijana (2 nights)
hire a car Lake Bled or Julian Alps ( 2 nights)
train to Venice 2 nights
Fly to Barcelona
So basically I'm trying to mix up coastal and interior, touristy and less touristy. We like trains, where I've not mentioned how we'll travel I'm assuming bus, share van or taxi depending on the country/costs. I have no interest in having a car in the city centres - but can drive on the wrong side of the road and drive a manual so will hire if it makes sense to .
We don't really need to hang on the beaches much as we'll have had time in Caribbean before we get to Europe. We are far more interested in history, food , art culture.
Still too busy? Have I gotthe balance in the various s cities about right?
