My bedroom door, and my oldest daughter's bedroom doors don't shut properly
When you say they don't shut properly, does that mean they can't somehow be tied shut also? I ask because I have one room also where the door doesn't shut right, it will just pop open if you walk by it. But there have been times where I had to lock one of my crew in there, for one reason or another, so I learned how to jam it shut, with one of those wedge things, then the only way to open it, is with me pulling the wedge out. Every one safe and sound, till I let them out.

Is there anyway you can do something like this with your doors?, Tie them shut, wedge them or something. With that many people there, I would have to lock them up, I'd be to worried that something or someone, might screw up, somehow. Just like last week, I thought the kitties where safe on the porch, till some idiot came over and left the porch door open, not thinking about cats and.......................Splash.......in the pool 2 kittens went.

Take no chances with the little ones.
