After leaving the hostel at 10, we got a Completo breakfast (the Chilean version of a hotdog, which is amazing) at Ravera, food court next to the plaza, before heading to the palace to see the change of guards.
At the palace, they do it big. There are around 40/50 soldiers playing in a fanfare, around 90 foot soldiers with rifles and 10 on horse with large spears. Whole show took like 25 minutes.
