I can't tell you how many people, including my wife's parents, questioned our sanity for going to Greece while they were having lots of protests.
But we never saw them. Luckily for us, they announce their protests so that they can get the most people possible. So we just stayed away from the areas with planned protests. We did see some people carrying a large banner once, but we were in a cab headed away from that area.
What we did see, however, were things on my bucket list. Namely, the Acropolis and the Parthanon.
But I got to see more. Like the Temple of Hephaistos.
And the Temple of Poseidon at Sounion.
It was a very cool visit!
