We were visiting Edinburgh castle and had tours planned at various times throughout the day around the area. We decided to jump in to Camera Obscura for a bit and it was so worth it because besides being 5 floors of showcases and activities, your ticket is good ALL DAY with IN / OUT PRIVILEGES! We saw what we could before our first tour, came back when it was over, saw more, another tour, saw the rest.
