From the logistics page of my trip report:
"Overall, we spent a whopping $2750 in cash from the ATM. A great deal of this was in the Galapagos Islands where almost everything was a cash transaction and nothing was cheap. Major Galapagos expenses included: $240 just to get in via airport/park fees, $475 for our hotel, $270 for 2 people to tour Isla Isabela, $90 for the Santa Cruz Highlands tour and $370 for the North Seymour Island tour."
Cash out of the ATM because credit cards were NOT the normal there. Turns out we did go to 3 "other" islands, (corrected from 4) 5 total including the one that houses the airport (you take a ferry across to the main island) and the main island itself. One was an extremely small piece of land next to Isla Isabella. Trip reports help to keep my memory in check!
A quick peek at this report and my pictures and I am better remembering the creatures. The huge tortoises and large iguanas WERE cool. It was a good trip. Trip prices quoted were for 2 people.
