Bus transfer from Bologna Airport to Rimini station is good, direct service, but buses not huge, only 32 seaters so advisable to book. Takes 1 and a half hours. Only stops once on way, 1st stop in Rimini is at the hospital, then the station. We'd booked the 4pm bus on Wednesday but just made the 2pm, and as he had room, he let us on. Cost 70 euros return, back on Tuesday. https://www.shuttleriminibologna.it/en/
