There's a possibility I might make a day trip to the park as part of a large group on a late-April Saturday. I fully expect the park to be packed, and was wondering just how necessary the Magic Bands are to the utilization of fastpass? Or do I just need the MyDisneyExperience app? I'd use Robb's patent-pending end-of-the-day trick, but other trips I've taken with this group tend to arrive late/leave early and I want to get around the park without feeling rushed (even if it means I miss the Flight of Passage queue). Also, does Dinosaur have a single-rider line?
