We are on the Jade. Several hundred folks were n the theater following instructions to disembark to get to the tour busses and private tours. We were to continue on deck 6, through the casino, to the restaurant and then down the stairs to deck 4, to the gangplank. The person in charge on the stage announced that we were to change directions and proceed directly down from 6 to 4 and then follow deck 4 corridor all the way back to the gangplank. There was a problem with disembarkcation, and we were in the corridor for 15 minutes. We were not moving, and then the announcement that there would be a crew fire drill. They closed the water tight doors at each end of the hallway, and we were trapped there. Some panic set in, and as we were released, many retreated to their cabins. It felt as if we were an experiment to see our reactions to being in a large group and being trapped. My wife wanted to turn around and go back but that was impossible as a couple hundred were stacked up behind us.
