re: Almalfi Coast Late February

The largest city is Naples which I wouldn't call Amalfi Coast. Personally, it's a city I'd never consider staying in. There are several towns you can stay in but none are cities.

You're picking the absolute worst time of the year to go there. It's going to be cold for the area and the ferry service will be spotty due to choppy seas. A lot of stores in towns will be closed.
