THIS may help…
Yes, the original AMS (for the X1 and P1 series) is enclosed with desiccant packs to help mitigate humidity.
Again, the P1S has a built in chamber fan that can help keep the chamber cooler when printing with PLA. If the chamber fan (for some reason) is just not cutting it, you can remove the top.
If the printer location is too low and you are worried about the children poking it from the top, buy some PETG and print a lid riser that will allow you to vent the top at will.
Yes, venting the top is the best option because P1P has the belt exposed and while not a big issue it’s still moving parts and if you want to later print other filaments requiring an enclosure you’ll be glad you purchased a P1S.
The smoked glass door of the P1S does not allow much to see though so a riser where you can not only install the AMS on top and allowing the lid to be tilted open or providing cooling slots but also install a led strip is the best you can do for the kids. They will be able to better see what is going on inside otherwise they may be a little disappointed by the low visibility provided by the original led and the smoked door.
I guess my experience has been different from everyone else. I have a P1S (upgraded from a P1P) and I print PLA with the door closed and the lid on all the time with no problems. I guess I’ve just been lucky? I got the P1P when they first became available to purchase after the Kickstarter. I originally had it in the ARC enclosure and never had a problem then either.
I do the same and have same experience but my outside temperature is nowhere near when the OP experiences as I’m am far from a tropical climate, at least not for days at a time.
