There will be 14 rooms. That is, one room for every 3-4 people. I don't think it will be a problem to avoid running into Korobeynikov.
p.s. Unfortunately, the 4th building can only accommodate 26 people, and we would have to split up into two buildings with people from this planet. Unlike us, they usually have some kind of schedule. With us, there will most likely be drunk and noisy people around the clock. That's why we will all be in the 5th building first (it can accommodate 49 people).
