The Wizarding World of Harry Potter TV Commercial, 'Nine and Three Quarters'

Two kids stand in Orlando Resort's Wizarding World of Harry Potter park, where the boy says to the girl he has waited his entire life to be there. The girl jokes back that it was only nine years, which he retorts back that it is nine and three quarters, referencing a number from Harry Potter. The park asks if you're ready for vacation you can't get anywhere else.
