EnglishUSA: you might want to try giving these people a call and see if they have any availability on the Eclipse cruise. They list it on their website. Also, the Starflyer is doing the Eclipse cruise too. Travelquest no longer seems to hold the charter as they have in previous eclipse years on the PG. I've been following these for a while as we were interested in an eclipse cruise too.
