That's trying to cram 3 full days into one really. I agree with Uwe that it would be impossible
Having been to Italy before making the choice of what to see & do is always tough.
I have had 3 non-successful attempts to get to Capri I am hoping to make it there this July.
Pompeii & Sorrento are both awesome too.
The Amalfi Cooast drive is just breathtaking.
Good Luck with your planning.
