My 2 sisters and I are taking our 9yo niece and 11 yo nephew to WDW in March over their Spring Break. Their parents are not going. They have been once before when they were 3 and 5. DNiece doesn't remember very much at all and DNephew only remembers some things. The last time their parents went and we gave them a box that had balloons, a toy plane, Disney back packs and Disney pjs in it. I want to do something different this time. I was thinking maybe a treasure hunt but can't think of what to put on the clues. We are going to tell them around Christmas as I want their input on fast passes and some of the fun of planning. Any ideas would be appreciated. Thank you.
