Hello: We are on a cruise and one port is Naples. We would like to do an affordable tour of Amalfi Coast. It is myself and 2 sons. We'd like to go from the port in Naples, drive along the coast and maybe stop at a beach somewhere to snorkel (Capri)? Is that lot to do? My teenage sons will not want to shop in the towns but rather view as we drive along etc. Any suggestions for a tour that sounds like this?
