We have a couple solo travellers going aboard MV Galaxy
for the fourteen (14) night "Exotic Mediterranean & Black Sea"
cruise round trip from Civitavecchia on 27 October 2007. Ports of call are the Greek isles of Mykonos, Santorini, and Rhodes, Istanbul and Kusadasi (for Ephesus) in Turkey, Yalta and Odessa in the Ukraine, and Piraeus (for Athens) and Naples (for Capri, Sorrento, Pompeii, and the Amalfi Coast).
It's not a formal "singles cruise" organized by an agency, but anybody else who would like to book on this cruise is more than welcome!
