Hello there. We're now in Mexico, and I'm still writing up our week in the Galápagos. I wanted to break radio silence quickly, though, to warn anybody who might be thinking about it not to trust Travelocity to book a rental car. Last weekend I used them to reserve a car at Budget, but when I arrived to pick up the car on Monday morning, they told me that they didn't have any cars available, and that Travelocity is notorious for making reservations without checking. There was also the small matter of the Budget location opening 90 minutes late, and then the customer service people directing me to another Budget location that also didn't have any cars, but at least the guy there phoned up a completely different rental agency that did have (very expensive) cars available, so it wasn't a complete disaster.
While I'm complaining, I should also warn you about kiwi.com, who seemed to offer a nice service for booking complicated air journeys across multiple airlines. We used them to fly from Quito to Medellín, but then discovered that they'd booked us on an airline that charges $15 to print out a boarding pass at the airport, and hadn't sent us the boarding passes for us to print out.
Thankfully, we eventually got refunds for both of these. Travelocity promptly refunded the deposit they'd taken. Kiwi took quite some persuading that we weren't trying to scam them somehow, but after several emails back and forth they eventually agreed to give us back the $30 we'd had to cough up in order to board in Quito.
