My family and I have vacationed in WDW more than a dozen times in the last 8 years. A month or 2 before we leave, I create a Disney Countdown that we mark off each morning so the children can see how many days are left before we go. Then as we wake up the children on the day we leave we have a big presentation while marking off the last day. The children love it and it helps stop the questions about how many days until we leave.
