We are planning to go to US for 4 days in June. Our two year old will have to sit out a lot of the rides. We also have a 7 year old - is there a baby swap or similar system? We will be staying onsite so we can use the "fast pass" feature but I didn't know if DD would be able to ride with both Mom and Dad. Maybe I don't need to worry about it because it sounds like 4 days will be plenty of time to do everything we want, even if we just have to take turns. Thanks for your input!
