>>2789567I did 4 days in Ireland back in 2021. Spent two days in Dublin, took a bus up to Giant's Causeway day 3, and went to Howth by train on day 4. I think something like that is ideal if you're staying in Dublin. The city isn't bad, but it's far from the most exciting place to visit. Two days was really all I needed. I could have maybe stretched it to three, but I'm glad I didn't. The two day trips really made the vacation though. In particular, I loved Howth. Ireland's Eye was awesome, as my wife and I had the entire island to ourselves for two hours (though I imagine this may be different with covid being done with), and the cliff walk was gorgeous. If that doesn't interest you, I'm sure there are other cool places you can get to.
