Basically, this topic is being created with one single purpose – to determine if there is demand for Moscow for CIS-2021, or if it doesn't make sense to bother and we should just go to St. Petersburg.
For now, the only option we're considering is:
Club-hotel "Voskresenskoe"
http://vsk-hotel.ru/
They want to have 100 guests (the initial preliminary calculation was based on the maximum), but we'll adjust their expectations. 100 people means that everything will be organized strictly for us and no one else. And in general, we don't really care about other guests, as long as we are the priority and have a separate space.
From July 31st to August 7th – preliminarily, it will cost around 25,000 per person: this includes a banquet and three meals a day (initially, a buffet was suggested, but I would reconsider this, as this format always means overpaying for food that remains uneaten).
Accommodation is for two people per room, with single beds. The price also includes access to the swimming pool, gym, and sauna. We don't have clarity on the halls yet (there are several halls, they sent us options today, and I chose three adjacent ones – a large one with 135 square meters, a conference room with 68 square meters, and a meeting room with 26 square meters) – but I believe these halls will be included in the price (the alternative for them is an empty or half-empty hotel).
During the summer, there are outdoor playgrounds for volleyball, basketball, and mini-football.
There are also additional paid options: bowling, fishing, billiards, ping-pong, a paintball field, etc.
Very close by (400 meters), right at the exit of the territory, there are Pятёрочка and Дикси stores (so you don't even have to go anywhere for basic alcohol).
Logistics – for Moscow, I would say it's ideal, as you can get there by minibus from the metro.
From Vnukovo Airport, it's 22 km on normal roads, 17 km through the fields (a taxi will cost 500-600 rubles during off-peak hours).
From Trёkh Vokzalov Square, it's an hour and a half by public transport (metro plus bus/minibus – an hour and a half is the maximum, including all waiting times and transfers between stops).
So, I'm attaching a poll – this is the price range that St. Petersburg has indicated. If people want Moscow, I will continue to look for options (four more venues, in addition to the current one, have received our requirements and wishes – but they are still working on proposals) and at the same time try to lower the price for the current option. In general, Voskresenskoe looks good at first glance.
