OK, here's one for ya. I loved it as a kid but I CANNOT remember the name. I remember a family is on vacation in Egypt I believe, and goes through some sort of "Dimension portal" or something. They end up in some wierd sci-fi world that seems kinda futuristic...Don't remember how long ago it was, but I remember it was Mom, Dad, a brother and a sister..?? Kinda sketchy but SOMEONE has to remember it!
