My daugher's birthday is June 13th, right after the end of the school year. We planned a Disney trip with our flight leaving the morning of the 13th, but our 11 year old had no clue what was going on. We had been to Disney several years before and she had loved the character dinner at the Crystal Palace.
So.....
We told her we were going out for her breakfast brunch on the 13th and left home in the minivan. All of our luggage was already packed and in the back of the van. She was still clueless. When we got to within 1-2 miles of the airport we handed her a birthday card and told her to open it and read it outloud. Inside the envelope was an invitation to her birthday dinner scheduled for 6:00 at the Crystal Palace on Main Street USA. As she was reading it and slowly realzing what was happening we hit Play on the van's DVD player and had our Disney vaction planner video was ready to go. You know that great introduction they always do...it's perfect for this.
She immediately began to cry and asked repeatedly "We're really going to Disney???" We handed her her Mickey ears and travel bag for the plane and we pulled into the airport parking garage. She said it was the best surprise ever, because she didn't have to wait months for it to come. The surprise and the vacation started right away.
The memories I have are priceless.
