My husband and I fly into Logan airport in Boston and are staying at the Winnstead Inn and Beach Resort in Harwich. We are trying to decide if we should rent a car at the airport or take the bus to Hyannis Transportation Center and rent a car there. We arrive on Friday afternoon. Our flight leaves Boston Monday morning at 11:30. Our biggest concerns are heavy traffic each way. If we do take the bus back to the airport is it reliable? 11:30 isn't that early but we would have to leave Harwich fairly early to get to the airport on time.
