I double-checked the RSSC press release section of their website. It confirms the Ring of Fire is the Mariner World Cruise 2009

Whew! A relief for booking PANDA 2 when it's available.

I'm holding space on those two legs; but I'd love to join in for PANDA 2, too. I'll have to make a decision when we know the details. There's room in our suitcase for two Honolulu doctors and my long-distance niece ... :D

Cheers, Anne
