Ciao Pat,

The first time I went to Roseto was many, many years ago. I was on a trip through Europe with a friend, and we stayed in Germany with her relatives. We went by train to Venice, then Rome, then Naples and from Naples took a bus to RV. The trip was only about a hundred miles, but it took all day driving through the hills and stopping in every little village along the way.
The last time I went to RV was about 12 years ago. This time I was on another extended trip, first stopping in Athens to visit friends. From Athens I went by train to Patria and took the overnight ferry boat to Brindisi, Italy; then went by train from there to Foggia. In Foggia, there were a couple of daily buses leaving from in front of the train station for Roseto, and as I remember the bus ride was a pleasant one-and-a-half hours. Of course, that was a dozen years ago, so you would want to check the connections ahead of time.
You could check train connections from Rome to Naples and from Rome to Foggia to see which would work best for you. I just remember that the bus ride from Naples to Roseto was long and rather grueling.

I hope this information is helpful, Pat.
