Question Dublin Itinerary and Recommendations for 4 Nights

Hi everyone—we will be in Dublin for 4 nights before heading elsewhere in Ireland this May. I’d love to hear your recommendations for must-see spots, hidden gems, and any local tips for making the most of our time. We’re into history, good food, and maybe a bit of nightlife. Also, any advice on day trips from Dublin that are worth the time? Looking forward to your suggestions!
