I'm planning a late March trip from Rome to see Naples, Amalfi, Pompeii, then return to Rome (not sure about including Capri). From Rick's book, it seems Sorrento should be my base for 3 nights. But I also see recommendations online to take a train to or from Salerno one way, and then Naples the other.
To avoid a one night stay, I was thinking of taking a train from Rome to Naples mid-morning, store bags, go to the museum and do Ricks' half walking tour, before taking the commuter train to Sorrento. Then do day trips to Pompeii and a ferry to see the Amalfi Coast.
Does that sound like a good idea, or should I plan for one night in Naples to avoid the bag drop/pickup and the commuter train to Sorrento in the same day?
Also, should I plan a way to go back from Salerno instead of Naples? We are a group of 4 with small backpacks and 1 carry-on size bag each.
Is there a part of the book I've skipped or need to re-read?
