I'm specifically thinking in our room (there are 5 of us, so it will be a category 4 room). What if, while we are soundly sleeping, the littlest stinker manages to get the door to the veranda open ~ right now, this thought has me waking in the middle of the night. I know I'm being paranoid, but I can't picture how high the railings might be, if they are "climb-able", etc. Can anyone help reassure me? Thanks!
