Florence to Amalfi

Puglia is very worthwhile! Coastal towns on the Adriatic, Polignano and Monopoli, plus historic Alberobello and Lecce.

Have you gotten yourself a guide book as suggested in one of your previous posts.

You seem to be trying to cover just way too much in your limited time.

rome2rio.com will give you some options on transport from place to place

Marla, you haven't engaged with the respondents who've previously weighed in about your trip, some who were concerned that you were trying to cover too much ground in too short a time. So, it's uncertain what your larger itinerary is now or what sort of budget you're working with?

Florence to Tropea is a looooong way. Amalfi (which doesn't have train or air service) is not a "stop" along the way and neither is the region of Puglia, if you were thinking of doing them en-route to Tropea in one day. What is "reasonable" for you and your friends' accommodation budgets?

You could also fly from Florence to Lamezia Terme, than a 55 minute train to Tropea.

The train (2 seperate trains), from Florence to Amalfi, is 41/2-5 hours. Using Trenitalia.com and https://www.sorrentoinsider.com/en/naples-to-sorrento-train-schedule

The train from Naples to Tropea 5 hr 07 minutes

To clarify what meant by Amalfi not having train or air service, that applies to the TOWN of Amalfi. Per Gerri's link, there is train service to Sorrento, which is near but not technically on the Amalfi COAST, and Salerno, which is also not quite "on" but is very close to the A.C.
