Hi, we think your best choice is Costa Rica. Manu, our fixer and location manager was the location manager for After Earth from Sony Pictures and other movies and shows for the Heyday, Studiocanal, BBC, VH1, Discovery Channel, Nat Geo, etc.
Costa Rica is very film friendly, permits are not complicated an the crew is the top of the line in Central America. You can check out our projects here: http://www.costaricafilminglocations.com
We´ve never worked in the Galapagos but we believe that as it´s a very protected area the permits would be quite hard to get and with many limitations.
