Along with the increased capacity, I organized a second tour through the castle. That way, both tours will be 40-50 participants which is more reasonable to follow than one giant guide leading a 90 players group.

An English speaking tour will be done with the topic of “Siege, Armor and Swordfight” – This tour will need some volunteers at some point. 😱
A German speaking tour will be done with the topic of “Frankenstein, Mary Shelley and what sinister experiments were done at Castle Frankenstein” – This tour will not need volunteers. 😅

Which tour you want to take can be decided ad-hoc on site.
