Naples + Salerno or Naples + Sorrento for 5-6nights (first time in Italy)?

Hi!! I’ll be in Italy for the first time Sept 28–Oct 3 (5-6nights) and I’m trying to figure out how to split the time. We’re thinking 1–2 nights in Naples and then 3–4 nights in either Salerno or Sorrento so we can really explore the Amalfi Coast.

Right now we’re considering:

• 2 nights Naples + 3 nights Salerno
• 2 nights Naples + 3 nights Sorrento
• or 1 night Naples + 4 nights in one of those

We also have family in Spigno Saturnia, which we’d love to visit. We’re not sure though, if staying in a small town like that would make it harder to experience all Italy has to offer on our first trip.

Our main priorities are great authentic food, local charm, and beautiful beaches. We’re not super into the major tourist traps or overly expensive spots, but we also don’t want to miss out on anything truly worth it either.

We’d probably only do 1–2 day trips: one to Pompeii and one to either Positano/Amalfi or maybe Capri (though I get seasick so I’m unsure about the ferry).

Would you recommend basing in Naples + Salerno or Naples + Sorrento? And would staying in Spigno Saturnia be too limiting for a first-timer?
