Regarding the drinking and other things, Vic is right here. That's why it became clear in St. Petersburg that two halls are necessary. Since attendees contribute to the "conference package," if they want to drink, they should do so in a designated area: neither you nor I, nor anyone else has the right to prohibit anything to adults who financially support the CIS. Because without the attendees, who now make up more than half, the CIS will not reach a quorum, meaning it will not take place (or will become even more expensive). Again, we have to consider that the audience is not getting any younger. And the dormitory accommodation format of 2011 is no longer suitable. That is, the average level of the venue suitable for hosting is increasing. Accordingly, the average price will also increase.
