We only had a short time in port because we were on a Repositioning Cruise from Civittavechia to Abu Dhabi and this was our last stop in Europe! Celebrity Constellation was leaving for Suez at 15.30 and the next port was Aquaba, Jordan three days away, so this was definitely not the day to get too foolhardy and be late back for the ship!! Constellation berthed in Piraeus the morning at Dock 12. Its a big port and Dock 12 is quite a way out so we took the free port shuttle as far as the Cruise terminal and then walked round to the station which is at the far side of the port. The walk took about forty minutes, and the station is easy to find, it is right by a large pedestrian bridge across the busy road – look for the big M for Metro.
