I'm going to Italy for two weeks at the end of June. We have 2-3 nights in Sorrento, Rome, Florence, and Venice. Does anyone have any tips for traveling to the country? I'm particularly worried about theft, especially because I'll be carrying a DSLR camera. Should this be a big concern (I've heard stories of people's credit cards being overcharged, wallets stolen) or am I making too much of it? Also, any day trip suggestions from these cities? Hopefully, we'll rent some bikes (I don't think I can go two weeks without riding ).
