Coming to Ecuador in September. Had planned to do an Amazon Tour but that trip has fallen through so scrambling to plan something else. Now planning to travel to Galapagos and do a land-based tour (DH does not want to do a cruise... on this trip, perhaps next time). Looking at a tour through Galapagos Islands... Santa Cruz, North Seymour and Bartholomew. Are these 3 islands a good "start" for a first trip to Galapagos? Will we "miss out" by not going to Isabela? Is this a good company to work with? Is there any other company you would recommend us checking out? Is there a different itinerary we should try to do? We can be in Galapagos 5-6 days. Thanks in advance for any help you can be with our last minute planning!
