I have spent half the day trying to sort out this one issue. Reading what seems like a thousand posts, I find that I am apparently not the only one confused. So it appears that the most common options are the 3-day pass that includes two free sites, 50% off other sites after that and unlimited travel on ????? Then there is the 7-day pass that includes most of the sites, but no travel. I am going to be in Sorrento for 7 full days, but the first one will be spent on Capri. So that leaves me 6 days. I'm thinking I should plan on two 3-day passes, but need someone to clarify a few things. So this relates only to the 3-day passes: do they give you unlimited travel on all SITA buses? Do they include travel on the Circumvesuvius trains? I will be taking the Regional train from Naples to Paestum -- will it cover that?
I have read there are actually 11 different Arte cards --- I'm going to ignore the other 9.
