Two weeks in Italy for our honeymoon
I spent a month in Italy starting in Naples and ending in Milan. If you wife likes movies then the boutique partenope hotel in Naples is fun on the waterfront area. I'd suggest a day trip to Capri for Blue Grotto from Naples. I did a great bike tour in Naples -I was the only person and ended up on Italian tv but that's another story. The underground tour was interesting -you definitely need google maps to find it.
I'd suggest Herculeaum from Naples too - as much as I love Pompeii this was a great surprise, less crowded and short train from Naples. I haven't posted about it yet but definitely a highlight
I have a ton of posts - food tours Florence, a fun unique Fiat500 tour, hotel reviews, etc on my blog (same as user name) and happy to help with further queries. I know private guides in Rome and Sorrento (for Sorrento and Amalfi Coast but as others have said long slow drive in July)
