I found this quote:

"Next, the hapless ship was chartered out to Starlite Cruises of Piraeus, Greece, for use as a casino ship between San Diego in California and Ensenada in Mexico."

It was on this website:

If you look closely at the picture of the ship, the smoke stack shows the bird logo.

So I guess it's Piraeus, Greece. I believe they used to have a website www.starlite.gr, but I can't even get it from the WayBack machine.
