Shoe, sounds like she is a bit scared of being alone. Maybe you can try and make a bed on the floor next to your bed with a night light, or try the night light in her room if she does not have one. They do get to a stadium that they get night terrors and can be afraid of being alone.
If you opt for the bed on the floor, just do it till you can see she is ready to move back again at night, but let her sleep in her room during the day in the holiday, just to show her that it is not all that bad.
Also have a checked out at the docter, sometimes they have a small infection you don't know of and this could also trigger crying and wanting to be with mommy in bed rather.
In the end it is a guess guess situation, but hopefully some of the above can help you solve it.
Good luck
