If you have to endure queues, try to opt for, or at least break things up with, ones that offer kids something to do while they wait. At The Many Adventures of Winnie the Pooh (toys) and Dumbo the Flying Elephant (play gym), for example, the waiting areas are factored into the overall experience.
Bonus tip: If someone in your party has to sit out a ride because a child doesn't want, or isn't tall enough, to go on it, take advantage of Rider Switch. Just have the ride-goer request a Rider Switch pass from the ticket collector. The person waiting can then use that pass to go through the Fastpass+ line without having to wait in line.
In other words, don't waste two Fastpasses on a ride two people have to take turns going on because one person will end up bypassing the line with Rider Switch anyway.
