Using AP bedroom as guest room

My au pair is traveling throughout the month of March. We are planning to have Company while she is away. Her bedroom was our previous guest room. I’m wondering if while she is not here we could have our guests stay in that room. I would of course change all bedding. My guests do not need access to any drawers or closets so her things would remain untouched. I would not do this secretly. I would tell her ahead of time, but I’m trying to get a gauge on her response based on your thoughts here. Is this crossing a boundary?

Editing for additional information: She will be across the country gone the entire month of March. There are no children that would be staying in the guest room. I would be telling her ahead of time so if there were any personal items she wanted to secure she could take them with her. The alternative arrangements are that I remove one of my other children from their bedrooms and have them camp out in the living room. Not impossible (and exactly what was done when the same guests visited when she was home), but seems silly to have an empty bedroom and not be able to use it.

I appreciate all your feedback though because I know if I ask her she’ll say yes but not necessarily mean it because she’s very accommodating. I want to make sure I’m not making her uncomfortable
