What to do?

Next Tuesday a good friend of mine is taking my kids for a sleep over (a day during the week). my husband works out of town monday-friday so I'll be here all alone Tuesday night into late afternoon Wednesday...as a mom of 2 toddlers I very much appreciate the free time but I'm also not sure what to do with my time away from everyone. Any suggestions on things to do? The point of her taking them is so I can kinda have like a self care day (her words) but idkkkk lol I have a nail appointment another day with friends so that's out. Everyone else works during the week so there's nobody to really hang with haha
