We traveled with my brother and his wife. One of us had been to London, and one had been to Ireland. We decided this was the perfect way to see England, Guernsey, Ireland, Northern Ireland, Scotland, and France, and we were right! The ship upgraded our rooms so we each had a balcony. Princess seemed to be very organized with their shore excursions. We took a couple of those, but also hired private drivers thru Tours by Locals for Belfast, Northern Ireland and for one day in Scotland. I would highly recommend them, as well as Woodford Chauffeur Cars, which we used getting to and from the ship. We also decided to tour on our own in Guernsey, Cork, Dublin, and Inverness, and got along fine. Hop-on, hop-off buses are good for getting around. We were so tired each day from our big excursions that we didn't go to many evening ship events. We ate in the dining room and enjoyed our meals. (Husband's complaint: They need to learn how to fix good oatmeal!) I got lots of tips from prior reviews, and really appreciated that. Now we just want to go back to Scotland, as it was so beautiful and we didn't get to see enough! Oh -- we split up on the final day in France. The women went to Paris, and the men went to see the Normandy beaches. Both were wonderful days, even though of course not enough time to see everything. We would definitely recommend this cruise to anyone who is a little timid about traveling. It's good to start with countries where they speak English (not that we could always understand them!) and you learn quickly that it's fun.
We visited Guernsey Island our first day out. We loved it! Rode the public bus to top of hill and spent quite a lot of time at the German Occupation Museum. Then we hiked back down the hill, enjoying the beautiful walk and stopping at the little shell chapel. Caught city bus back down to dock. If you go, be sure to read "The Guernsey Literary and Potato Peel Pie Society" before you go! It helps you understand the history during WWII.
Cobh is a darling little town. The museum just as you get off the ship is excellent! Info about building the Titanic, and lots about the trials of the Irish. We walked all over Cobh, seeing the beautiful cathedral, and then hired a taxi to take us to see the Blarney Castle and a bit of Cork. Blarney Castle itself is sitting in a gorgeous setting, even if you don't want to kiss the Blarney stone. You need to be fairly fit to climb the castle.
At Greenock/Glasgow, we took the tour bus to see the Falkirk Wheel and the town of Stirling. Both were wonderful. We toured the Stirling Castle. It is being restored, so couldn't see all of it. Ate lunch at the Portcullis restaurant.
At Invergordon, we took a bus into Inverness and had a great day on our own. Found a pub with the family name so had lunch there. There is a great little shopping mall tucked inside a block in the main part of town where we did much of our memento shopping. There is a beautiful river all through the town, and we walked across it on a walking bridge.
