If things ever get back to normal I would like to visit Italy in 2022. So far, my plan is to establish a base camp in Rome and from there make several day trips via train and bus to the surrounding towns. Is it possible to make a day trip to Paestum from Rome and come back that same nigh? Or would it be better to leave Rome late in the afternoon, spend the night at Paestum, and then return to Rome in the afternoon after sightseeing the temples? Any advice or tips will be greatly appreciated.
