When we were there in May, I asked one of the CMs why they took the chimneys out and replaced it with a cloudy misty type area instead. He said the part at the beginning where you go through the chimneys seemed to be the part that made most people with motion sickness sick. My husband who never gets motion sickness gets a little queasy anytime he rides FJ though and still did, even without the chimney part. Knowing it had made him nauseous previous trips I had given him a meclizine the night before and another one that morning before leaving the resort. This is a man who has never gotten sick on a ride in his life. He has no problem with Tea Cups, Star Tours, Sum of All Thrills, the old Body Tours, Simpsons, or Spiderman, and loves any coaster or spinning ride ever made, but for some reason FJ does him in.
