Yes ma'am, though I'm not sure it was technically a ferry. Took the boat past the Cliffs on my way back to Shannon, too. That I shouldn't have done-it was too late in the season. We got caught in a storm, everyone was sick (I almost got sick) & nobody saw the Cliffs (we were too busy trying to not get sick in addition to the foggy rain, so even had I been outside, I couldn't have seen anything). Aw, shucks. I'll just have to go back!
Oh nooo but yes, you'll have to come back there is Blenheim palace where the live Cinderella was filmed that would be gorgeous to visit in the summer months- and the castles in Scotland that inspired brave! (You've got me thinking of a Disney bucket list now!)
