#2 - He can't even enter the queue if he's not tall enough so there's no reason at all to include him. Sometime before 7:00 prepare your party by selecting just those who plan to ride. Or technically you will deselect those who do not plan to ride. MDE will automatically select all in your party who have an Epcot reservation for that day. For the small child, uncheck their name1. Would you recommend only one person in the group trying for a BG? Would it mess up with multiple people within the same party trying on different devices for a BG at 7 am?
2. Is rider-swap used on this ride? We have a small child in our party who is not tall enough. Should I even bother including him in the BG? Or can we still do rider-swap if we select adults only in MDE?
