Well guys I'm gonna do some math here and be sexist.
First math:
So, we can probably get rooms with 2 beds, and we can share beds or have some people sleep on the floor, so we can get, lets say 5 people per room.
Now, lets assume I can get 4 rooms (since that seems to be what I see most), that'd house roughly 20 people.
Now, lets be sexist:
Ladies get rooms first, then guys, because I like ladies more than I like guys. And Jens gets a room too if he wants. Because he said I was cool.
