Hi Rachel! Thanks for visiting the Disney Parks Moms Panel.
  While many 
attractions at Walt Disney World Resort have minimum height requirements, none of the attractions in Magic Kingdom Park, Epcot, Disney's Hollywood Studios, or Disney's Animal Kingdom have maximum height restrictions. There are a few attractions at 
Disney's Water Parks such as 
Tike's Peak at Disney's Blizzard Beach and 
Ketchakiddee Creek at Disney's Typhoon Lagoon that have maximum height restrictions. 
 For the most part, taller guests should have no problem boarding any attractions. The biggest issue might be tight legroom. I suggest taking a peek at the ride vehicle prior to boarding, and if you spot an area with a bit more space, ask the Cast Member to assign you to that row. Especially in the case of a boat-style attraction such as 
Pirates of the Caribbean or 
Frozen Ever After, you might find more leg room in the front row. For Space Mountain, the middle or rear seat has a bit more space for long legs. One attraction that seems particularly tight to me is 
Astro Orbiter, and I'm not even tall! Besides leg room, I would also be careful with any rides that have a metal lap bar. You just want to be sure no knees are bumped. 
 I hope that helps! Let us know if you have any additional questions.
