Can't remember the cost but we did this on our British Isles cruise a couple years ago. The HoHo was great. Maybe we spent a bit too much time at the Guiness Brewery. The tour finishes atop the brewery where you are given a pint of Guiness. Not to insult the true beer lovers but it was really bad ! I'm a Miiler light type of beer guy ! I also think some of the Alaskan beers are good. Dublin is a great city and by all means do the HoHo.
