We stayed at Camping Sant Antonio in Vico Equence last year. Situated on an old Marina you can get the ferry to Capri out side the gates. Windy road of about three quarters of a mile down to the site just take your time. we took a 7.8 meter twin axle. Have a look on Google maps. The owner will take you up to the station at the top of the hill, no charge, walk back but it is down hill. Sorrento. Pompeii. Naples all easy and the train is very cheap. Best pizza ever 9 euro and the owner delivers to the van door. ACSI site.
