I went when I was five months pregnant with dh, ds4, dd2. Yes, I planned it after finding out. I'd go with 10 kids and pregnant...I'd find a way!!! One thing my dr. recommended and really made a difference for me was a wide brimmed straw hat...maybe not the most fashionable thing in the world but they've got better ones now! Actually, one of the only rides I "disobeyed" the warning sign on was the Safari and it was no big deal...I just braced my legs and let my arms absorb alot of the bumping (I didn't think it was very bumpy anyway) and loved it. By the way, last year we, along with my sister's family, were scheduled to go in October, but found out I was pregnant with my 4th and due in October! I actually called her from the delivery room on her cell phone while she was in Magic Kingdom to announce the birth of her newest nephew!!! (Thinking about them being at Magic Kingdom that day was a real distraction!) We're (me, dh, ds8, dd6, dd3, ds10mos) are going back in August! You will have a blast! Oh yeah, we were so pleased with how accomodating people were on the transportation. It was one time I was thankful that I looked 15 mos. pregnant at only 5 mos!!!
