1. Based this trip in Dublin for a few reasons. Some bad some good. Dublin is fucking expensive. Ireland overall is $$$. Whatever you think you budget should be 3.5x it.
2. Crazy drivers in Dublin. Small roads. Nowhere to park. I did not get a car thankfully. Charge you to park as well.
3. Bus tours have been awesome. Cliffs of Moher, Blarney Castle, Giants Causeway. 3 separate 12 hour day trips with multiple stops.
4. A travel adapter is the lifeblood of the trip as they have G plugs. Also, some tour buses have USB ports to charge phones.
5. Food is mostly bland, service is slow. Expect 1.5 hours to eat even if you’re seated right away.
6. Beautiful country though. Very interesting your sites.
7. If I did it again, would spend 1-2 nights tops in Dublin. Definitely don’t recommend a car anywhere narrow roads.
