While we haven't traveled with any of the organizations you listed, we just nailed down a Galapagos cruise ourself - March 3-10, 2004 - with Sangay Travel.

The office is located in Quito and they were very helpful with the cruise. The purpose of this e-mail is to suggest you plan SOON because all the best vessels get filled early. It took us 4 days to find the right vessel for us and the right date! The rest of our trip is independent of a tour group.
