My brother recently surprised our parents by secretly taking his own family to surprise them on a trip to
Disneyland. They surprised each child by telling them one at a time a few days before and then their youngest got to sneak up on the grandparents while they were sitting down for lunch in California Adventure. They have it on video and it is so fun. The kids loved seeing the confused and surprised looks on their grandparents faces and my parents talk about how fun it was to be the ones that were surprised instead of planning the surprise.
