[@Bishop]Aw man, I'm sorry. XD we should have established that really. My bad.
It's still daytime but that's not to say your character can't be exhausted if you don't want to change your post.

As for the time spent in the cabin, I think it's safe to assume people have arrived at different times. We haven't specified when each character got there, so you can be creative. So far, it seems that some were there ~3 days while others are still exploring or getting to know people. 
I hope that helps.
