Hey @dakidski, just in case you missed: it seems the party place is going to be in the Raivola hotel (https://www.raivola.spb.ru/). It is outside of the city (about 38 min by train). So I would consider to book a room in the Raivola hotel itself when time comes. Or at least in the Roshchino where it is located (https://en.wikipedia.org/wiki/Roshchino,_Leningrad_Oblast).
