I'd say about 10... I can always move my sofa... I can probably borrow some chairs, but I don't know about the tables... I only have a low sofa table and a normal sized dinner table... Maybe someone have a folding table they could bring in their car or something... Or we'll just sit on the floor
It would have to be on a Saturday, and an "uneven numbered week"
(Like this is week #9)
I hate "cancelers" and "lates" so only serious joiners! I imagine meeting up around 11-12 AM and gaming etc. till late evening, possibly even continuing on Sunday, if you bring an air-mattress

There are a shopping centre right around the corner where we can get food and beverages
I live in Rødovre (7 km from Copenhagen downtown)
