Search for a venue
Why not book a hall! most village halls are very cheap to hire for a few hours. Perfect for winter Birthday parties or summer infact!
Below are a couple of links for local halls and venues, please check the height of the venue ceiling to make sure the castle you are going to hire will fit.
