Hi,
I know there's a number of folks who still haven't booked their room / are confused about it. It looks like there isn't a roommates wiki page so I created one:
https://fedoraproject.org/wiki/Flock2016-Krakow-proposal/Roommates
I also checked with the hotel, Best Western Premier Hotel in Krakow (btw their English is great,) and they have between 11-29 rooms left under our rate depending on arrival and departure dates.
If they run out of rooms by the time you book, you can book at: Best Western Efekt Express Hotel +48 12 614 57 00 Opolska 14, 31-323 Kraków, Poland
It is next door to the Best Western.
Hope this helps folks.
