The actual tour was fabulous and the tour guide was very informative. The complaint I have is that the documentation provided when the tour was purchased did not tell us what company was actually doing the tour so we did not know which of the multiple buses at the port was the one we were contracted with. Better information and documentation would have eliminated the stress and confusion we experienced.
What a thrill to walk past the long line and go right into the Guinness Storehouse. Well worth booking through Viator
