What would be the best way, mode of transportation, from Cork Airport to Shannon Airport? We are planning to visit Ireland and then Paris at the very first of October. We can't get a flight out of Shannon to Paris (via Ryanair due to cost) so we have been advised to fly out of Cork. However, we will have to turn in our rental car before leaving Ireland and hate to rent one just to get back to Shannon for our flight home to the U.S. Anyone have any suggestions? Thanks!
