For a 17-year old it was hilarious to watch my parents and grandparents act out a interview on television. We all sat down to watch an old video of us at Disney and then my mom broke in as a reporter-type thing. She asked my grandparents their favorite things about Disney and then they started talking about how much they wanted to go again. Then they yelled out that they wanted to go at Christmas. I thought it was a lot of fun. Other ways my grandparents have told me is by wrapping up planning videos, books, etc. in wrapping paper for birthdays and Christmas. I had a friend whose parents didn't tell them until the morning they left for the airport, except they didn't get to go because it happened to be on Sept. 11, but that was a cool idea too.
