For the record, my daughter won these park hoppers through Radio Disney. We went down for Memorial Day and the night before DL I sat bolt-upright in bed, looked at my wife and said: "Did you pack the tickets???!!!" She sat bolt-upright and said, "No! I thought you did!"
We sat there in stunned silence trying to think of what to do. Of course, our kids were in the next bed over, sleeping soundly and no doubt dreaming of meeting Mickey the following morning. We decided to buy park hoppers at the gate. Ouch.
So, now we're trying to recoup some of our losses.
