Just a heads up on your Cork stop, please check where the ship docks, it is usually in a town called Cobh off to the south east about 10-15 miles away, so it's certainly not a walkable distance, although the area is pleaseant enough, albeit remote, to walk around.
I remember Cork as being a vibrant city, but spent most of the time in bars tasting the various versions of Stout - all very nice.
If the ship is calling into Cobh and you wanted to do your own thing, there is a train service running directly from the port into Cork. But the port of Cobh also has a lot of Titanic related history and a few good bars
All the best,
