Not exactly horror-horror, but a lot of bad moments.
There was a tour to Prague with a visit to Dresden on the way back. Head Zanko Lesya I can’t say that something terrible happened, no one was forgotten, everyone returned, but in general the organization of the tour was bad. If in other groups the bus was waiting for tourists, then it was always the other way around and force majeure had nothing to do with it - they cannot happen every day.
