A greedy plan for 3 nights and 4 days around Naples

#EuropeExploration Day 1: Naples From Rome to Naples by ITALO high-speed train. (It takes about 70 minutes. I took the train that arrived after 13:00.) After visiting the Naples National Museum, I visited the Royal Palace and other places. Day 2: Pompeii, Herculaneum First, I headed to Pompeii by the Vesuvian Circumferential Railway. It takes about 40 minutes from Piazza Garibaldi Station. Pompeii is crowded, so I recommend making a reservation in advance. I took the train that departed from Garibaldi Station after 8:00 am so that I would arrive with plenty of time to spare before the 9:00 am opening time. The most convenient station for sightseeing on the Vesuvian Circumferential Railway is Pompei Scavi - Villa Dei Misteri Station. Be careful not to confuse it with other stations. If you want to take your time sightseeing in Pompeii, you should plan on spending 5 hours. Even if you just want to take a quick look, it will take at least 3 hours. I used the Pompeii Plus ticket to see the Villa of the Mysteries and other places, so it took a long time. For lunch, I ate a sandwich I bought at the supermarket, then took the Vesuvian Circumferential Railway from Pompei Scavi - Villa Dei Misteri to Ercolano Scavi. Depending on the time of day, you may be able to go directly, or you may need to transfer. I returned to Pompei Scavi - Villa Dei Misteri after 2 p.m., but there was no direct train nearby, so I changed trains at Torre Annunziata and headed to Ercolano Scavi station. It's about a 20-minute walk from here to the Herculaneum ruins. I think it will take about an hour to sightsee here if you're quick, or about two hours if you take your time. Piazza Garibaldi station, which is directly connected to Naples Central Station, is about 20 minutes away by the Vesuvian Circumferential Railway from Ercolano Scavi station, so it's very close. Day 3: Amalfi, Positano I booked a tour that combined buses and ferries. As far as I could see, the cheapest tour you can go to is around 60 euros. I took the tour that departed at 8:20am and arrived in Naples at 5:30pm. After that, I had dinner and returned to Rome.
