Goodness, you must be new to the GCC region. Family day means "bachelors" and notably (as Weasel said ABBSAM bachelors) are not allowed to enter the malls. It has nothing to do with entertainment for your family.

BTW my father always took us somewhere "free" - the beach, walks in the woods, skating and tobogganing in winter, etc. etc. where he was able to interact with us (and he usually took our friends too, every weekend). What do you do with your children in a mall to build a relationship? I'm not saying that you can't do so there, but it boggles the mind that you would want to especially as the weather is good right now?
