My wife and I (early 30's) will be making a day trip from Rome to Naples sometime during our time in Rome (10/18-10/24). We've already booked early entry to Vatican on the Friday so that leaves Wed/Thu or Sat/Sun for a full day trip.
This will be our first time in Italy together so we're trying to hit the big sites of Rome but we don't have our Rome itinerary nailed down yet. We're still deciding on Pompeii but leaning towards skipping in favor of more time in Naples. In Naples, we definitely want to do the Archaeological Museum (as maybe a substitute for Pompeii) and Rick's walk, maybe the port and definitely some churches. We would would also like to attend a church service on Sunday whether Naples or Rome.
Would it be better to get weekend vibes in Naples and avoid the crowds of Rome? i.e. prioritize some of the museums in Rome during the weekday? Maybe it's a better vibe with less people in Naples during the work week or the museum is a madhouse on weekends?
