Caitlyn is visiting Florida. From her hotel (0,0) she decided to go for a walk and see what's around. She walks 4 blocks east and 4 blocks north to the beach. She then walks 5 blocks west and 3 blocks north to the closest Victoria Secret for a new bikini. Caitlyn finally walks to a restaurant 2 blocks east and 4 blocks south of Victoria Secret. How many blocks is she from her hotel?
