Just one Christmas to remember!

As a teacher and a single mom of three beautiful kids...I want just once for them to experience a magical stress-free Christmas!  They have always wanted to go to Disney World and to see Diagon Alley. We tried saving change in a homemade piggybank but I had to have my wisdom teeth out so the piggybank had to die.  Every year I try hard to make Christmas fun.  We never go on vacattion in the summers (we have tried to camp on our townhouse patio lol) And every year as both Mom and Dad to my kids I have to play Scrooge "sorry you cant put that on your list you have to pick something small".  My eleven year old son saved his birthday money and gave it to me last Christmas to help play the credit card bill.....He said, "Don't worry Mommy one day when I'm famous I'm going to take you to the happiest place on earth and I'll pay for everything!" So here goes nothing.....Please help me give my kids just this one Christmas to remember!
