There will be three of us, myself, my daughter and 4 year old Grandson. I suffer from severe motion sickness so I won't be able to accompany them on some of the rides. I have read about ride swapping, but I'm not sure how that works. For example on Dumbo (I know tame for most, but I just can't do even gentle circle rides) could my daughter take my Grandson with their fast passes then take him again on mine or would that require him to have an extra fast pass?
If I were to just skip signing up for one FP and let them ride Dumbo would that screw us up from getting additional fast passes. Must all of us sign up for 3 before anyone can get more?
