How does Rider switch work at Universal and Islands of Adventure? We will be travel with a 10 month old and also another child who wont quite reach the requirement for all of the rides. We will be staying at Portofino, so we'll be using our express pass when available. How would this work for rides such as MIB,Escape from Gringotts,Transformers, Forbbidden Journey,Jurassic Park,Spiderman, High in the sky trolley train ride? Also lets say there is a group of 8 of us... and 1 person stays out with the baby. How many can go back onto the ride with the person who sat out?? How does that work? Thanks so much, the more detail on what to do the better!
