I am trying to prioritize fastpasses and make it so we aren't walking all over the parks each day nd am finding it frustraiting. So Hollywood Studios and Epcot have tiered fastpasses. I can manage Hollywood Studios (although we're still walking all over the park) but Epcot I'm having trouble with. If I only grab one fastpass now and after it's used on our park day can I grab the next tier one fastpass? Is that worth it or would that be a waste?
