We are taking our kids (9, 6, 20 mo) to WDW for the first time and will be hitting most of the big rides. For rides that we cannot take the baby on, we will be doing the child swap. My oldest has already told me she does not want to sit by herself. So, which rides can fit only 2 people in one row? I am assuming for child swap, we can't even wait in line with them to see how many can fit on the ride, correct?
