Believe me tiggerbella, I feel your pain.
Thanks for having your friend checking the Spanish sites.
My LDS got the same message from Ken. "We should here something soon, and I expect this to get resolved shortly." was the basic message. It is about what I expect at this point: a positive note to keep our hopes up, and keep us from inundating him with emails and phone calls. At least he is providing some information and contact to people who booked through Galapagos Adventures. That is a good thing. Just ask our friends from the UK and CZ how frustrated they are with little or no information about their trips.
Realistically, divers are the minority of tourist to Galapagos. I remember Ken's letter stated 128,000 tourist a year visit the Galapagos. The decision that has us developing spastic colons only affects around 20,000 divers. Many are booked a year or two from now, probably do not frequent message SCUBA message boards and have no idea about the situation. We are the minority of the minority of tourists, and the attention our situation is receiving reflects that. If the 100,000 land tourist were affected, I'm sure you would see more coverage. It is crumby, but it is the reality of the situation. Our emergency just isn't an emergency to the rest of the planet.
All we can do is what you stated. Keep calling, e-mailing, making a pest of yourself, and post the information you obtain here to keep others informed.
As far as insurance goes, I'm not aware of a trip insurance that will cover a situation like this.
