We had a large group and Janez handled all of us in stride. He even customized the tour on the fly to accommodate a special request that cropped up, making one particular member of our party very happy. It was a relief to have a professional driver handle the narrow mountain passes and high volume of traffic in the popular spots, all without making our very car-sick-prone companion ill. 10 out of 10 for safe driving skills! Janez added a lot of depth and color to the locations we visited by providing anecdotes, folklore, and sharing his personal experiences. The history and culture lovers among us were thrilled. We would have missed out on a deeper understanding without his knowledge and willingness to share. I honestly can't think of any "constructive criticism" to mention. I mean he even went into businesses to check on availability and locate alternatives for us. We only speak English so this was a major time saver. And considering he put in a 12 hour day (maybe more depending on his commute), our entire party truly appreciated his hospitality and spirit. It was simply a wonderful day and we can't thank him enough.
