Temple open house question

We live within walking of a temple that will be having an open house soon. We were still TBM when construction started, and my kids (5yo and 3yo) have spent the majority of their lives watching the progress on it and wondering when it will be done. We are thinking of taking them to the open house to satisfy their curiosity and demystify it a little, so the temple doesn't become this big special mystery in their minds. The one thing I am worried about is the messaging that will be present at the open house. The last open house o went to (Provo City Center, I think?) had some kind of video presentation all about temple doctrine. Has anyone been to an open house lately? Do you know if they still play a similar video? And is it something little kids would understand and latch onto, or would it go right over their heads?
