Thanks C.F.! I knew someone could help, but I hated seeing the question go unanswered. I wish I had read the question again and spotted the Explorer of the Seas... That would have told me that it was a RCCL cruise. But you are correct in needing to know where the person is traveling from before being able to say if the train or the bus is cheaper...
