i realize they are sometimes relatively cheaper, but other than that is there any benefit?
probably a better idea to go with the flow and not pigeonhole yourself into strict timelines, no?
for reference the trains i'll need are:
Rome --> Florence on arrival day (don't plan on buying due to uncertainly of landing, customs, etc.)
Florence --> Siena (bus - tickets needed in advance?)
Chiusi --> Salerno
Salerno --> Rome
thanks all!
