Do hotels in Naples usually have arranged excursions to Sorrento, Capri, Pompeii?

The tours are run by other agencies, not the hotels themselves. For example: http://www.viator.com/Naples-tours/Day-Trips-and-Excursions/d508-g5 , http://www.initaly.com/info/monzillo/monzillo.htm However, you can very easily do any of these on your own without having to pay for a tour. The Circumvesuviana train line goes from Naples to Sorrento and there's a stop at Pompeii along the way. There's a trip planner here: http://www.vesuviana.it/web/en From Napoli Centrale station (Garibaldi) to Sorrento takes about an hour and costs € 3.40. The Pompeii stop is Pompei - Scavi Villa Misteri. That takes about a half hour and costs € 2.40. The entrance to the ruins is a short walk from the station. You can find ferry schedules from Naples to Cpari and back here: http://www.capri.net/en/ferry-schedule. The ssie has a lot of very good information on things to see and do in Capri as well.

well it depends, usually they do, but if not they of ourse have contacts of agencies that do it. u can find wherever around there. anyway visit all of them, they're fantastic! i've been in all of them, a real natural wonder!
