We had been to Rome before, but we did take the bus to the Vatican to see it again. Very impressive. We stayed at a nice little bed and breakfast near the airport called Casa del Sol. Nothing fancy but quite adequate - 15 euro cab ride to and from the airport.
We loved Genoa. On the day we were there (a Sunday) they happened to be having an open house (all free) at every palace and museum in town. That was very fun! We also took the funicular to the top of the mountain and got a great view and a good pint of beer. We used the ship's shuttle bus to and from the ship which was only $10 per person for all day use. Walking in town was easy. Beautiful cathedrals, too. What a beautiful city!
We took a boat ride from the ship to the town - $25 each round trip. We then walked about 1/2 mile to a little train that took us up to the Notre Dame Cathedral overlooking the city (cost was 7 euro each). They dropped us off at the top of the mountain next to the cathedral and then we could spend as much time as we wanted there. Trains left about every 30 minutes to come back. The train ride included commentary all the way up and back - very interesting except it was given in about 6 different languages so you had to wait for your language at each stop. The Notre Dame Cathedral is spectacular and the view is even better!!! Very much worth the trip. Marseille is a beautiful city and very easy to get around in. Very fun!!
We had been to Barcelona before a couple of times so we only had a few things we really wanted to do. We took the ship's shuttle bus to the monument at the end of La Rambla and walked around a bit then went to our favorite restaurant - Les Quince Nits in Placa Real - for lunch. Fantastic paella and nice vino outside on the patio! Primo!! We then took the subway to La Segrada Familia which was amazing despite the long wait and the 20 euro each cost. We have taken the hop on hop off bus in Barcelona before and it is a very good value also if you have the time.
This is a pretty boring port. Not a whole lot to see that interested us. We took the city bus from the ship to town (about 3 miles) and then walked around a bit and came back to the ship. This was the only disappointing port.
