If you have children, this is a fantastic place, I'd imagine children would love this place to bits. However, as an adult there isn't a massive amount to see that you probably haven't seen... until you get to the roof and the camera obscura itself. Personally, I was thinking the ticket even with its all day return was a bit steep until I got to the roof, it's worth the ticket price to keep a wonderful bit of Victorian engineering maintained and operational. The staff were friendly and entertaining, and all the exhibits were interesting.

I'd say the highlights for me were the camera obscura, and the vortex tunnel. If you like optical illusions, Victorian curiosities or have children, it's worth a visit.
