This quote pretty much says it all!
"Disney isn't asleep at the wheel when it comes to queue technology. It reportedly invested $1 billion in the MyMagic+ platform that powers the MagicBands that facilitate park entrance and FastPass access. However, with some Disney visitors fretting about the advance planning that it takes to maximize the FastPass perk, it's neat to see a high-tech digital solution that can be fired up on the fly."
