We went with awning windows to overcome this issue
Awning windows are also restricted when on 2nd floor with no security screens...
We've just added ceiling fan provisioning for hot nights, so we're not running the AC all the time, so crack a window and turn the fan on
We did this in the kids room. Wish we did in ours too
