Well worth the money to bypass the lines for Book of Kells! Be sure to read all the banners as you enter the hall so you will be able to appreciate the Book. It is of the 4 Gospels, but is only open to 1 page, so it is best to read all the entryway to have a full appreciation of the Book. Continue on through the library, which is old world charm, all wood paneled and will close soon to be fully renovated. Lots of insightful information available. Then, we walked through town. Our tour guide Dermott was knowledgable and very entertaining. We sung Mollie Malone by the statue, then continued to the Dublin Castle. Well worth the money!
