If you can find the Water Ferry, I highly recommend buying a roundtrip ticket to Capri. It's not too far off the coast and you can buy a variety of tickets (fast and slow ferry) so you can get there for under $15. It will get you out of Naples when you get tired of the filth and Capri is simply beautiful. Plus, if you can manage to stay the night in Capri, all the tourists clear out around 6pm and the island completely changes. about 9 years ago
For one of the best chocolate shops in all of Paris, go to une dimanche a Paris (http://www.un-dimanche-a-paris.com/) They have incorporated the old city wall into their structure and have a beautiful facility. They have home made hot chocolate and the most friendly staff. (never forget: always open a conversation with Bonjour Madame/ Monsieur .....even if you butcher the rest of your French, it matters that you tried.) This chocolate shop is also located on the street where the guillotine was first installed and is very close to the notre dame. A very historic area. about 9 years ago
Are any major sights in Paris closed, restricted or undergoing restoration this month? Anything covered in scaffolding?
Musee d'Orsay was a few months back about 9 years ago
