Straying away from the city to be teleported to Peter's absolutely beautiful castle is an experience that my wife and I will never forget. Sure, the castle is ridiculously stunning, but there are few words to match its incredible history, tangible magic, and unprecedented company.
When I grow up, I want to be just like Peter. If you don't go for the castle (which you totally should, duh), then go simply to meet an amazing man with even more amazing stories. Not sure if we'll ever make it to Ireland again, but Peter and his castle give us all the more reason why we should.
