Waiting in line for Star Tours years ago, I once saw the cast members in a flurry around a young pregnant woman. I would guess she was somewhere around six-seven months, and they had a section of the hallway sectioned off right before you go into the ride. The lady was laying on the floor, where people usually stand in line, and she was in pain and not looking good.. I don't know what happened, if she had been on the ride, or just been in line. But after seeing that, I realized that those signs of when not to go on rides should be taken seriously and not blown off. If she had just been in line, and something happened, what would have happened if she had been on the ride? If your not a local, traveling and staying at DW, can be a physical undertaking for anyone, and is total out of your normal routine. What might be similar to things you do at home, might have a different effect after walking all day, sleeping in a new place, being jostled multiple times on different rides, a change of diet, the heat, and how easy it is to get a little dehydrated. No one thing might be a problem, but lump all the stresses together can be rough on any person let alone someone in their third tri. Please take it easy
