The best flights for me to Venice/Rome had a lay over in Dublin/a US city and the flights were a little over $1300. So instead I booked a round trip ticket non stop to Dublin. With Skyscanner I booked a flight from Dublin to Venice and then Rome to Dublin. Both tickets combined were less than $1000. So I took my $300 dollar savings and booked three nights at the Paramount Hotel in Dublin.
At some point I want to do a thorough tour of Ireland. This time I just want to explore Dublin. My flight should get me to my hotel by 2pm. I thought about booking the Literary Pub Crawl that night. The next two days book and explore the sights with the 48 hour hop on hop off bus. Day 2 see Kilmainham Goal, I'll book the tickets online before I go and also book a time for the Book of Wells also day 2. Day three I'd like to take the four hour Malahide Castle and coastal tour. I also really hope to listen to an evening musical event if they have one at Christ Church Cathedral.
Is there anything else you'd recommend?
