Bought a BIRG ticket and took the regional train into Rome. This is one port where I would suggest you take HOHO bus or some other tour. It was just too big to do on foot in so little time. The metro stops are far apart and do not serve the historical centre. We got lost for a good part of the day and ended up missing a lot of what we wanted to see.
I was pleasantly surprised by Marseille. After having read so many comments from other cruisers about skipping the port and going somewhere else I wasn't expecting much. After spending such long days in Italy we just decided to take the cruise ship's shuttle into the Vieux Port. The shopping was actually quite good here as were the little cafes surrounding the port. It was a nice relaxing day. We had a little trouble when the cab drivers staged an impromptu strike, but I thought the shuttle bus drivers did a good job working around them trying to get everyone back to the ship.
We took the cruise ship's shuttle into town. Again, very well organized and frequent service.
Palma was the best stop on the trip. It was one of the most beautiful places I have visited. Lovely little shops in the old town, lush gardens, gorgeous fountains - beauty everywhere. I highly recommend getting off the ship in this port. If you miss this one it would be a real shame.
