We also had a good day in Alexandia. We got a private guide (from the ship) so we could walk at our own pace. And it really worked for us. We went to Pompei's Pillar, the catacombs, the roman ruins (theatre and baths), the gardens and palaces and the fort...all in 4 hours. But it wasn't rushed and we spent enough time at all places.
We ate in Portfino's last night and did enjoy the atmosphere and the food. Looking forward to the changing themes as we continue the journey.
One thing has struck me so far about the staff...they are even friendlier than I remember! Most introduce themselves and make sure they know your name if they haven't met you before. There are smiles all around and the service has been fantastic. This is really a happy ship!
