20+ including locals? You should write how many people requested accommodation in total. So we can understand how much it will cost per person – 100 hryvnias or more.
I already wrote, if nothing changes – 4000 hryvnias per day = 16000 hryvnias for the entire period. The cost per day of accommodation will be 200-250 hryvnias per person.
Initially, I would like to determine who among the visitors needs accommodation. After that, we will deal with the people from Kyiv – I think we will figure it out.
