I read through the entire thread, and it's more of a pointless argument than a discussion about the CIS region :( Roughly, the cost per person is 12,000 + 2,500 + 1,750 + 3,500 + 1,250 = 21,000 (this includes only lunches and excludes dinners/barbecues/tournament fees/excursions/alcohol/poker, as well as the cost of tickets). Tickets cost 9,000, and you need at least 10-15,000 for pocket money, so the total cost is around 40-45,000. I'll have to think about it.

Am I understanding correctly that the minimum cost per participant is 19,000, excluding food and the tournament fee?

It's a little more than that, Kostya, because the calculation included the fact that the girl doesn't pay for the venue.
