We will be travelling to the UK in July (14 days not including arrival/departure days). Flying in/out of London (no option for open jaw, due to ticket type restrictions). We are not planning to spend much time in London, maybe 2 nights, then will head to Scotland for 3-4 nights. This should leave us 5-6 nights in Ireland before we return to London the day before our departure flight.
My husband has been to Dublin before, and would prefer to go to Cork, but has suggested that I do some research to see if there is anything I feel I must see in Dublin so that we can go there if I really want to. Based on the articles I'm reading, I'm leaning towards skipping Dublin and spending our time in Cork and taking some day trips from there.
Is there anything that I absolutely MUST see/do in Dublin that would warrant a day there?
