Translation of activate in Spanish

The airport was huge, compared to Siem Reap's one, of course. We expected something similar to Bangkok's airfield but it was completely different. We stood in line for the passport control.
Banteay Srey was beautiful. It was a very small temple but it had a lot of detail in it. Simathay explained everything. He was truly a great tour guide and we were happy that we had met him.
If you want we can exchange messages and emails in English and Spanish in order to improve and get some exercise. I think we should correct each other's messages. i need to practice otherwise I will forget everything.
