When you say you are a "family for late 20's kids," I assume that there will be 4 people, two kids in their 20's, and two parents 40-60 years old.

That being said, the Amalfi Coast is a place to relax. Sorrento is all tourist kitsch. It's OK to be based there then get out, but it's over the top in tourism. You can say that about Venice and Florence, but those cities are large enough to provide you with respite from tourism if you just stay away from central areas, like Piazza San Marco. Up in the hills there are some nice areas, but Sorrento is basically a fake gelato and limoncello place for tourists coming in on cruise ships. It's not Italy.

If you make too many side trips, you'll be exhausted. I think Naples is a little too far away, but not if you really want to do it for a pizza day, and to walk along the water. Naples is one of the most beautiful cities in Italy. It's unbelievably fantastic. I'd take a few hours there over a few weeks in Sorrento.

You should go to Pompeii.

Positano + Amalfi + Ravello in one day, seems to me, to be a nightmare. Positano deserves a day, where you go there and hang out. It will be too cold to swim and lie on the beach, and it's a 50-50 chance that it will rain in November on any given day, so there will be no lounging at the beach.

Most of the boats to anywhere, including Capri, no longer function in November. The water gets too rough, and they are closed for the season. I don't know when you are going in November, early or late, but the boats don't go once the weather turns.

Ravello is very shut down in November, depending on whether it's early or late in the month. Eat before you go there, because there are not likely to be any restaurants open. They are shut down for the season. You can walk around for a few blocks, and that's it. Everything is closed. In the summer it is great, but not so much in November. It is way, way up in the mountains on top of the Amalfi Coast. It's a fun bus rid, with lots of fine sights to see of the water, provided it's not too rainy. But it's a place that exists for summer festivals, then it closes and wraps itself up into a cocoon until the next summer.

Definitely Pompeii, Positano, and also see Amalfi, and just relax. Don't worry about how many cities and sites you can fit in during a four day trip.

Riding the bus from Sorrento to Positano or Amalfi is great fun. It's a wild, wild, beautiful, but safe ride. One of the most beautiful rides in the world. I guess you can hire a car, but the bus is dirt cheap, and it won't be crowded in November. Heading south, get seats in the front and right of the bus. You'll have drop dead beautiful scenery. Since it's only a few euro's get off and on whenever you like, e.g, Positano, Amalfi.

Salerno is not my favorite place on the Amalfi Coast, and in November when the beach is not happening, it's a long bus ride, but has some things to see because it is a fairly big city. ou can visit Paestum, old Greek ruins that rival the Parthenon, and that are from the 7th century BC, about 500 years older than Pompeii. Since it's a big city and a functioning port not a cruise ship port, it won't be as shut down in November as the other Amalfi Coast towns. Most important, you'll get out of super-touristy Sorrento, and you'll be able to walk in the historic center of a real Italian city, go to Castello Arechi, and good museums.

There's not much to Sorrento except for it being a touristy cruise ship port. The drive from Sorrento to Positano and Amalfi is the famous one. Do that. And since you only have four days, just find ways to relax. In my opinion, use Sorrento as a base, and find a way to get out of there because for the most part, it exists for tourists.
