We had breakfast and then went off to explore Malta. When you get off the ship the tourist office is set up in the terminal with maps and information.
As you walk along the pier there are loads of stalls to purchase excursions.
We chose to do the hop on hop off bus tour from Malta sightseeing it was 10 euros per person and worth every penny. We chose the north route and sat back and listened to the comentary which was available in 6 languages. Mdina and Rabat were truely beautiful.
The same tour on the ship was 49 euros so the one at the port was well worth it
When you arrive at the terminal the port provides a free shuttle service to the tourist office at the entrance to the port. If you are planning on going into Rome then walk straight out of the gate along the see front for 5 mins and the train station is on the left hand side. The train is just 20 euros return.
We chose just to stay in Civitavecchia as the weather was dreadful. There is a small tourist train that will take you around the town (not sure of the cost) We just walked around the town as it was market day and the town is very pretty.
