After a bit more research, it appears that there are two ferry companies to the Aran Islands - Arandirect & Aran Island Ferries. It looks to me as though they both have a bus from Merchants Rd. (a block away from the bus/train station) and both have the same bus and ferry times. The only difference I can see is Arandirect has electric stabilizers for a smoother ride and is slightly more expensive. Am I correct in my understanding? Does anyone recommend one ferry over the other in terms of reliability?
