If you knew my driving resume you'd know it's not the driving ;-) Resume aside, a couple years ago we actually drove the Iceland Ring Road, over 2000 miles on the car in 10 days, but this is a different kind of trip. We plan to make short 2 day hops town to town. Having been there yourself, would you drive from Milan or Lake Como to the Dolomites for 2 nights? We do need a car for a couple of spots we're thinking about, but we are looking forward to train travel as well. I did watch a solo hikers youtube that described a long day taking a couple trains and a bus to get up into the mountains, so my excessive comment was sorta based on that persons story and the fact that we don't care to drive 6-7 hours, twice in a couple days. Knowing I love the mountains my family suggested the Dolomites should be a separate trip in the future, looking forward to that!
