Have just returned from our holidays and we have discovered an alternative to driving all the way.
We found a ferry that went from Igoumenista in Greece to Venice.
It was like a mini cruise with very good amenities including a swimming pool that we declined at this time of year
It left Greece at 7am and arrived in Venice at 7.30am, local time,
the following day. You can then drive onwards or choose to spend a couple of days in Venice.
When we added up the overnight hotels, fuel, tolls and taxes of the overland route it worked out to be only a little more expensive and certainly more relaxing.
If you are bringing a dog over with you to Turkey the kennels were very clean and well set up and much better than the Turkish company ferry that we used from Ancona to Cesme, which was a deck locker/store room so the dogs were locked in at night.
After driving back overland through snow blizzards and terrible roads(in Serbia and Bulgaria especially) we will take the ferry every time from now on.
It took us 1 day to get to Canakkale, crossed border at Ipsala the next morning into Greece and then a days drive on empty motorways to reach Ipsala.
Hope some of you find this useful info.
