So we’ve never had to use rider swap but we will need to on our upcoming trip. How does it work with ILL? We have to buy for the two kids if we all want to wait together? I’m assuming they can’t come thru the line without paying first? Can the adult who is waiting with the kids have another adult wait with them so they don’t have to ride by themselves? Same with Genie plus? We add the kids on and then use the switch when it’s our turn? Thanks for any help!
