I was there on September 11th in the MK.....
We knew before the parks closed as we saw a lot of people on phones and there was a general something is wrong feeling in the park. I was in Fantasyland when my DH called his office to find out what was going on, and they told him. We called relatives on our cell who gave us the whole story. It was very surreal...Parents were grabbing kids and heading out, characters were out in Fantasyland and seemed amazed no one much was coming to visit with them, I saw more than one whisper to their helper CM I assume asking what was going on...
We were heading out anyway when they made the announcement that due to unforeseen circumstances the parks were closing for the rest of the day. At the exits the CMs were handing out free passes to those of us with Park Hoppers who were losing a day on our hoppers...
All the parks closed and someone thought DD stayed open, it did not...they blocked off the parking lot to the entire DD and Marketplace area with road blocks and guards so no one could go in there..I know we tried to drive over there and found it closed and guarded by CM Security guards.
Most of the local malls and a lot of stores closed too,
Walmart was open and we went there in the afternoon, just to get out somewhere, it was packed with tourists all looking kinda numb..
It was a scary time and I will never forget it or where I was...
