I have agreed to host the post-prom sleepover. 11 girls and 5 boys. They will be arriving around 4:30am after the after prom event.

I am wondering if I should communicate with the parents of the kids who will be staying here, as not all of them know me and my husband.
I was thinking about things like:
all the kids will be sleeping on the main floor of the house
either my husband or I will be here at all times
there will be no underage drinking permitted
we will provide basic toiletries like shampoo/conditioner/face wash/makeup remover/shaving cream/razors in all of the bathrooms so the kids don't have to pack that kind of stuff
we don't have firearms in our house
its a non-smoking house (my son has asthma, so this is always a concern for me)
we have a dog (allergies)
we will most likely be a gluten free kitchen by that time
What do you think? Would you want to hear from me? Or would you just trust that your kid was making a good choice about the group they were hanging with and leave it at that?
