We are visit Ireland in late August following our sons wedding in London. We will have roughly 1.5 days in Dublin and we are booked on a Hop On Hop Off bus to get us started. I understand that many of the top tourist spots are within relative easy walking distance, but I am wondering if there is a general direction that these buses usually go. We will probably catch the bus at the National Museum of Ireland. The spots we want to take in, in no particular order will be The Book of Kells, Dublin Castle, St. Patricks Cathedral, City Hall, St. Stephens Green, Christ Church Cathedral, and if possible Kilmainham Gaol.
So I'm asking probably a difficult question, but if we do get on at the National Museum, what would you think the next closest place of the ones I have listed might be? I'm trying to maximize our limited time and be ready before we arrive.
