Two more observations: They hint at "I've Had The Time of My Life" with an instrumental version when Baby is checking out the place in the beginning and sees Max Kellerman telling the waiters to give the daughters a good time--even the dogs and that the "Mambo Magic" hotel dance is the same dance as the finale--with different music. And obviously it changes by the end, but at the start it is the same dance--with different music, which makes sense. They're not going to go up there and do something totally new, they're going to do the dance they rehearsed. And it's cool, watching them side-by-side; how stiff and awkward the first dance is, compared to the "No One Puts Baby In a Corner" dance.
