The Cruise was OK just not up to the Celebrity standards we are used to.
We did private tours in Scotland and Liverpool. The Fab Four tour is a mist if you are a Beatles fan.
The Dublin stop was a disaster. The ship should have told us the traffic was bad. We spent three hours on the Shuttle and the ship left at 4:30. Not enough time. we did the Guinness and Dublin Castle tours and they were great.
