Factual error: Maleficent states that Princess Aurora will prick her finger on a spindle - the part of a spinning wheel that holds the bobbin. Spindles aren't sharp; what Aurora actually pricks her finger on is the distaff, which is used to hold the fiber before it is spun.
Factual error: Phillip cuts through the thorny mess on his way to the castle by swinging his sword from side to side. He and his mount then advance without harm through the overgrowth. Cutting to the left and right would not clear the path directly in front of them.
Answer: Being that Aurora is a princess, she would have many servants and other attendants constantly tending to her. They could conceivably discover the spinning wheel and prevent Aurora from pricking her finger inside her bedroom. Luring her into the tower makes her more vulnerable. It also adds to the story's drama and suspense.
