Oh gosh no that’s not enough time in Rome,
Add a minimum of 4 nights, probably still not enough
Sorrento 3-4 minimum if you want to day trip to Pompeii, Capri, Naples?
Amalfi 2-3 or really whatever time you can give it.
Travel by train from Rome, use ferries and buses or private driver on Amalfi
We spent 4 nights Sorrento, 2 Amalfi, 1 Ravello , 2 Salerno
It was great
Not sure where that particular tour ends- if Rome, you could head to Sorrento/Amalfi after just those 2 days in Rome on the tour-then return to Rome for 3-4? Nights before flying out of Rome
OR
Stay in Rome extra days right after tour, then add Sorrento/ Amalfi and fly home form Naples.
You’ll want to be in your departure city the night before your flight, so plan accordingly.
