Santorini is one of those iconic destinations that is on just about every traveler's list. It's a unique place, and you have to see it for yourself to be able to appreciate the hype.
This hype, however, means that you and the rest of the world seem to be here all at the same time. Fira (or Thira) in particular can get incredibly busy, especially when there is more than one cruise ship anchored in the bay below. The good news, however, is that cruise ship passengers are notorious for not venturing very far from the tour bus drop-off point, so grab a scooter and head for Oia, on the northwestern tip of the island, for some elbow room and a chance to appreciate the stark beauty and incredible light of this island.
