Luego de nuestra visita a Copacabana e Isla del Sol…
In repeating from memory the (now extended) conversations in the Travelogue, I'm substituting without even thinking about it the above phrase with:
Después de haber visto Copacabana e Isla del Sol…
Una vez que hayamos visitado Copacabana e Isla del Sol…
That's just one example, but the grammatical structure of those last two phrases are from other lessons in the course - tangibly demonstrating that the Travelogue is really working.
