We are flying into Naples on July 3 and wanted to go to Pompeii or Herculaneum and the Archeological Museum before heading to the Amalfi Coast the next day. Now I've realized that all three sites will be free since it is the first Sunday of the month and I've read the crowds at Pompeii have been huge on previous free Sundays. I'm hoping that because the crowds at the museum and Herculaneum are not as big as Pompeii that we can still enjoy those on a free Sunday. But I haven't seen any information on how the free days affect them. Right now our plan is Naples Sunday night, take the Circumvesuviana to the coast on Monday, stay there and take TrenItalia to Rome on the morning of the 6th.
Any advice on how to fit a visit to the museum and either Pompeii or Herculaneum?
Thanks!
