I've read that on rides with height requirements, one parent can go on the ride while the other stays with a child who doesn't meet the req's & then the other parent can ride on the next turn. I was wondering if anyone knows if that is the only reason why you can use the child swap or baby swap option. We are going to Disney next week with our 4 & 5 year old girls. I am also pregnant so there are rides (mostly likely the ones with height req's) that I won't be able to ride on. Do you think, if both my daughters meet the height req's & it's a 2 person per car ride, that they would let me wait with one daughter & then let my husband take the 2nd one on the next ride? I would be really excited if they did!
