Anne - hmmm, maybe I'm getting confused. I was assuming that the Ring of Fire cruise was the Grand Circle Pacific. If the Ring of Fire is actually the 2009 Mariner world cruise, then you're right. I'm only really concerned about the GCP since that would be PANDA 2 and would be miffed if I booked, couldn't go, and got socked $250 cancellation penalty.
Actually, the more I think about it, you're absolutely correct and I have my head up my nether region. ;)
Anne - I just noticed your sig - you booked Sydney to Hong Kong?? (green with envy)
