Hi Ladies,
I did both options when I did the tour neatly 3 years ago and really enjoyed them.
A small group of us went to Ljubljana and had a lovely day, the guided tour was very good and it is a beautiful place, there is ample time for looking around and having lunch - remember to take Euros with you.
I was very lucky to have Vlatka (V) as my tour guide and she is amazing. We also had Branco as our driver and together they made a brilliant team, even doing an unplanned detour and stopping for a short time at Predjama Castle so we could see it. I would love to go back.
Hope you have a lovely time.
Caroline
