Hi! 10 of us are traveling to Italy this summer. Looking for suggestions for transportation from Rome to Bari and then Bari to Amalfi coast.

Ciao @Toni Howard29 I agree with Robert's answer!

Best way from Rome to Bari is by train and a private transfer from Bari to the Amalfi coast.

We can definitely help you arrange group rates for the train as well as transfers and tours for your group! There is a great Pompeii tour that includes lunch in a vineyard and transportation back to Rome that I think you would absolutely love to finish off your time in Amalfi.

Let me know if you have any other questions, we are happy to help however we can!

Roma to Bari the train is the best, about 5 hours. Go, business class, Very lovely.
Bari to Amalfi is not going to work. 
You go Bari to Naples and stay in this hotel for the night Starhotels Terminus  5 star. 
Then get a tour bus to Amalfi Coast. 10-hour day. They will pick you all up at this hotel. Lots of stops, free time. Pictures. 
Stay another night or two at the Starhotel Terminus and do Pompeii and Herculaneum
 

Enjoy
