Solo late 60s woman here. I can't do hills which I think is the case in Sorrento, and anyway I'm not sure I'd like the "holiday" vibe. Also I'd go well off season either November or February and things might be closed there anyway, which would be disappointing!
I was thinking of Pompeii itself, or Salerno. Would anyone know if they would be suitable i.e. not shut down off season, or could you recommend anywhere else? I need to be on the train line and I'm not sure I'd like Naples itself, although I will spend the last day there to see the museum.
Sorry for being so picky, but would love to hear from anyone with suggestions.
