Arrived!
...even if quite groggily. I zipped right through customs, took some money out, and at the inexplicably simple push-of-a-green-button, I was released!...to the hoards of taxi drivers. I'm waiting in the airport until dawn, however, before I head out on an adventure/find a hotel. I asked several people when it would amanecer (to become dawn), and answers greatly varied between an hour and a half (6am) to "in the next 5 minutes is should start to get clear outside". 8am was another guestimate, so I guess I'll just have to see for myself!
