@Lash,
Actually, does a 36 year old woman, who has been married before, need anyone to walk her down the aisle to "give her away"?
I think she should walk down the aisle by herself, accompanied by her little bridesmaids.
But, Prince Charles by her side will certainly make the festivities appear somewhat traditional, and even more regal, and will show that she is already considered a member of the Royal family.
I'm glad that the wedding is tomorrow, I'm actually getting bored with all the hype--it's been too repetitive, not very informative, and, consequently, not very interesting..
