I will be arriving at Shannon Airport at 8 a.m. on a Sunday morning. From there I plan on taking a bus to Galway. Where is the best place to change my U.S. dollars for Euros to get started? In the States, I can purchase what they call a Tip Pak from Triple A. Present cost is 78 Euros for $127. They are charging an extra $20 for the Tip Pak. That's not really a bargain.
