As for your question" "I was interested in seeing the Dolomites, but if youtube is accurate the travel seems excessive for our 10 day trip?"

We drove a rental car all through the Dolomites for a week. It was spectacular, to say the least.

But we are from Colorado and used to driving in the mountains, with the twisty roads and no guard rail drop offs.

I don't know why a YouTube video would seem excessive though? I tend not to rely on videos, ha ha!
