If you want to see frigate birds (red bulging sack under throat that sometimes is inflated); blue footed boobies and waved albatross, along with some marine iguanas; a unique red sand beach, and giant tortoises that are in large enclosures and not wild, this itinerary offers a nice variety.

Any snorkeling?

Probably no red footed boobies, no Galapagos penguins, no fur seals but you will see lots of sea lions, no massive mess (group term) of iguanas. Less likely to see whales.

For the average visitor who wants to see/photograph some of the famed Galapagos critters, experience the islands, and not spend a whole lot of time there, this should be a good trip. A real nature enthusiast should spend more time.

Thanks for the advice. I was thinking of itineraries covering Isabella, Fernandina as well, but they are a lot more expensive.
