This is the most convenient port. Free Wifi access at the port terminal. There's a tourist info desk, Tram/bus/metro right in front of the terminal. We bought "Genoa pass" for EUR4.50. Took bus 18 to Castelletto, took a lift up (included in the Genoa pass), for a birds eye view of the city. Then walked around the small pedestrian streets, and the Old Port before taking the metro back to the ship. I'm surprised MSC sells the Aquarium ticket for EUR22.90 (vs EUR26 at the Aquarium).
