Is this a live in shelter? Or do we have to be gone in the day...and is it first come first serve?

Hello is this for family's also? My wife n son

Hello haley. I work at the shelter. Yes it's a live in shelter And its first come first serve. If we are full and you ask to stay. We will politely tell you that we are full. But if we have a bed avaiable then you will be able to stay.

So what is a live in shelter?
