The Dark Side of the Dom: ghost tour with Freewalk Cologne

I found the tour a little boring - the information given was boring and the tour guide himself, though perfectly nice, had a boring enough personality and seemed unsure of himself a lot of the time. The guide also seemed to ignore me when doing the check-ins though he looked directly at me but continued with other people and then came to me last. I found this quite rude, especially when I was on my own so I didn't feel that welcome from the off.
