Need trip planning help! Western Canada to Vegas/Anaheim..

Thanks for your help, I appreciate your suggestions. I have been to CA before (by plane), but have never been to LV, I can't see spending much time there but would like to at least see the strip, ditto the other locales, even though I realize they would be very quick. We need to get to CA to visit family, and really want to spend a few days at Disneyland with the kids. Other than that our route/destinations are quite flexible. :)
