You can contact hamleh Al Ansari to arrange umra visas for your family. The price last summer was 100 riyals per person (by air was 200) and you need a picture for each person who is going. I would advise you NOT to drive at night. During the day is ok but the roads are dangerous at night. You may want to drive to Riyadh (about 8 hours away), get a hotel for the night and drive the other 8 the next day.
