Give it a try, put a bed next to yours, or let her in bed with you, whatever you want, put a baby gate up on the doorway and tell her to lay down.
I felt guilty like you because i work all day so ive never crated any of mine at night. When i turn off the lights and both me and my husband are in bed, they all get in there spots and go to sleep. If one of us are awake, they are restless and stay up until both of us are in bed
I wouldnt have her in a separate room, she will want to be where you are. She might not settle if she isnt in your room
