<p>We did this two years ago, with the pool in the backyard as well.</p>
<p>First, once I agreed to do this, I had many parents calling me (and profusely thanking me) to offer food, etc. for the evening. Take them up on it when offered. We actually went the fondue theme route, so I did have to borrow some fondue sets. I think there was one young man who wasn’t allowed to stay the night due to an early morning obligation, and his dad came to pick him up (he told me when he arrived that night). Daughter had been very articulate that no crashers were allowed. If you came, you stayed, or there would be a phone call to your parents by me. </p>
<p>Our prom is always held on a Friday, and while it is an early release day, most of the kids have been up since before 7AM, and by the time they arrive at your house… with nice comfy couches, a TV, and some munchies, I found they didn’t have that much energy. We really heated the pool so it was almost like a hot tub, which added further to the drowsyness. You probably won’t have to worry too much about boistrous kids - they’re going to be exhausted. Some magical transformation happens when they change out of their formal wear into their flannels PJs. </p>
<p>However, for sleeping arrangements, the boys slept in the finished basement, and the girls scattered between the first floor and second floor. I strategically positioned myself at the top of the basement stairs once everyone was settled (perhaps between 4-5AM) on a makeshift ‘resting’ spot, and maybe catnapped for an hour or two. When husband woke up around 6:30AM, it became his shift, and I headed up to bed for a couple of hours sleep. When the kids started getting up, I got up, got the breakfast stuff ready, and stayed up until the last kids left (before lunch). As soon as they were gone, I went back to bed and slept another 4-5 hours. </p>
<p>I don’t know if taking keys is worth it; kids are on to that rule. They bring two sets, give you one, then still have a set on them. Because of how our house is laid out, I was able to dead-bolt the front and back door once everyone was asleep, yet I was positioned such that, had an emergency occured, I had easy access to both front and back doors to unlock them if anyone needed to get out. </p>
<p>The rest of the weekend was awash for me, but it was worth it.</p>
<p>Not all adults can manage this, but I’ve hosted several co-ed sleepovers (cast parties, etc.), with pretty much the same rules, and for the most part, they’ve been successful. I also am always offered lots of help from other parents regarding supplies, etc., and sometimes their social presence earlier in the night.</p>
