We were there for the castle and would have enjoyed seeing the castle even more in the daylight. For my wife and I, the history of the castle was fascinating and we would love to have seen it all!
The "ghost" portion of the tour was a negative for me and a few others, yet many others loved the idea of the possibility of ghosts in the castle. I myself feel that the orbs were nothing more than lighting in a dusty environment. I would recommend the tour of the castle during the day, other events such as escape rooms, proms, weddings, etc. yet I would never do a "ghost tour" again.
