Unless I'm mistaken, I don't see that you've posted any pictures of Trevi Fountain. When I was in Rome about 16 years ago, the fountain was being dredged so I didn't get a chance to see it in operation. Also, when you went to Pompeii, did you have a chance to get to Sorrento, Capri or the Amalfi Coast? If so, would love to see some pictures.
We did not get to the places you mentioned, but did climb Vesuvius
