Next time I will use another tour operator.
Bought a tour 2 months before departure. A week later, they clarified whether nothing had changed. We bought train tickets in both directions ... We received the documents in 2 days, and then it turns out that the airport has changed from Zhulyan to Boryspil and the departure time there from 15 to 17 hours, and back from 7 pm to 7 am. Thus "stole" half the night and half a day of rest.
